rxrpc: Only disconnect calls in the I/O thread
Only perform call disconnection in the I/O thread to reduce the locking
requirement.
This is the first part of a fix for a race that exists between call
connection and call disconnection whereby the data transmission code adds
the call to the peer error distribution list after the call has been
disconnected (say by the rxrpc socket getting closed).
The fix is to complete the process of moving call connection, data
transmission and call disconnection into the I/O thread and thus forcibly
serialising them.
Note that the issue may predate the overhaul to an I/O thread model that
were included in the merge window for v6.2, but the timing is very much
changed by the change given below.

rxrpc: Only set/transmit aborts in the I/O thread
Only set the abort call completion state in the I/O thread and only transmit ABORT packets from there. rxrpc_abort_call() can then be made to actually send the packet. Further, ABORT packets should only be sent if the call has been exposed to the network (ie. at least one attempted DATA transmission has occurred for it).

rxrpc: Make the local endpoint hold a ref on a connected call
Make the local endpoint and it's I/O thread hold a reference on a connected call until that call is disconnected. Without this, we're reliant on either the AF_RXRPC socket to hold a ref (which is dropped when the call is released) or a queued work item to hold a ref (the work item is being replaced with the I/O thread).

cxl/pci: Move tracepoint definitions to drivers/cxl/core/
CXL is using tracepoints for reporting RAS capability register payloads for AER events, and has plans to use tracepoints for the output payload of Get Poison List and Get Event Records commands. For organization purposes it would be nice to keep those all under a single + local CXL trace system. This also organization also potentially helps in the future when CXL drivers expand beyond generic memory expanders, however that would also entail a move away from the expander-specific cxl_dev_state context, save that for later. Note that the powerpc-specific drivers/misc/cxl/ also defines a 'cxl' trace system, however, it is unlikely that a single platform will ever load both drivers simultaneously.

rxrpc: Fix a couple of potential use-after-frees
At the end of rxrpc_recvmsg(), if a call is found, the call is put and then
a trace line is emitted referencing that call in a couple of places - but
the call may have been deallocated by the time those traces happen.
Fix this by stashing the call debug_id in a variable and passing that to
the tracepoint rather than the call pointer.

rseq: Extend struct rseq with numa node id
Adding the NUMA node id to struct rseq is a straightforward thing to do, and a good way to figure out if anything in the user-space ecosystem prevents extending struct rseq. This NUMA node id field allows memory allocators such as tcmalloc to take advantage of fast access to the current NUMA node id to perform NUMA-aware memory allocation. It can also be useful for implementing fast-paths for NUMA-aware user-space mutexes. It also allows implementing getcpu(2) purely in user-space.

Tracing updates for 6.2:
- Add options to the osnoise tracer
o panic_on_stop option that panics the kernel if osnoise is greater than some
user defined threshold.
o preempt option, to test noise while preemption is disabled
o irq option, to test noise when interrupts are disabled
- Add .percent and .graph suffix to histograms to give different outputs
- Add nohitcount to disable showing hitcount in histogram output
- Add new __cpumask() to trace event fields to annotate that a unsigned long
array is a cpumask to user space and should be treated as one.
- Add trace_trigger kernel command line parameter to enable trace event
triggers at boot up. Useful to trace stack traces, disable tracing and take
snapshots.
- Fix x86/kmmio mmio tracer to work with the updates to lockdep
- Unify the panic and die notifiers
- Add back ftrace_expect reference that is used to extract more information in
the ftrace_bug() code.
- Have trigger filter parsing errors show up in the tracing error log.
- Updated MAINTAINERS file to add kernel tracing mailing list and patchwork
info
- Use IDA to keep track of event type numbers.
- And minor fixes and clean ups

* Enable the per-vcpu dirty-ring tracking mechanism, together with an option to keep the good old dirty log around for pages that are dirtied by something other than a vcpu. * Switch to the relaxed parallel fault handling, using RCU to delay page table reclaim and giving better performance under load. * Relax the MTE ABI, allowing a VMM to use the MAP_SHARED mapping option, which multi-process VMMs such as crosvm rely on (see merge commit |

f2fs-for-6.2-rc1
In this round, we've added two features: 1) F2FS_IOC_START_ATOMIC_REPLACE and 2) per-block age-based extent cache. 1) is a variant of the previous atomic write feature which guarantees a per-file atomicity. It would be more efficient than AtomicFile implementation in Android framework. 2) implements another type of extent cache in memory which keeps the per-block age in a file, so that block allocator could split the hot and cold data blocks more accurately. Enhancement: - introduce F2FS_IOC_START_ATOMIC_REPLACE - refactor extent_cache to add a new per-block-age-based extent cache support - introduce discard_urgent_util, gc_mode, max_ordered_discard sysfs knobs - add proc entry to show discard_plist info - optimize iteration over sparse directories - add barrier mount option Bug fix - avoid victim selection from previous victim section - fix to enable compress for newly created file if extension matches - set zstd compress level correctly - initialize locks early in f2fs_fill_super() to fix bugs reported by syzbot - correct i_size change for atomic writes - allow to read node block after shutdown - allow to set compression for inlined file - fix gc mode when gc_urgent_high_remaining is 1 - should put a page when checking the summary info Minor fixes and various clean-ups in GC, discard, debugfs, sysfs, and doc. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAmOaTNUACgkQQBSofoJI UNIQnw//V7Q8DUHw5YNj04jutwXH2DNMLAmn/NJh5S6dIzy/LiywlSzVg53/0/FP 4K577urUkIhgilRO+yncUMSnSQk7BluQvGSx4ja2AV+dpDomjxM3GwIacGzSvr7D VfVf8Vig10UEFrrtEEKtv1VFlYHAmo8lLpubzrZHV8aZFLHHYO2fakQhPu8BYsaz eGCJwxjvTZcQUPkaeG9tWto3ChI3F6PzreiQ5TztHhLWSEgw/o0qijpsc+2SthaV my7uGjeBY8EGPeSYbeCxRtdx8g8Qu11K3ISuDj8zBybmjG3IWOGt1CVcrY6tZbal aL70CMtHkMqMn03VqbpCTqBtdWNMrrw5sYSL3qXIUdXlX/2yJBh9fLAeNxKNs5Nu 6veSb2WgYMHqIsClkAAcP0xJ8g6kodGoG60wVr4ek0Vdt4osaQqwq+bnffpwwxtQ F+7aRuinv+rdrHJ4CuFXAmHPKh2lBe2lTTWZEKg2RptTxZ5DhD2Qn6x1khPD2GFA mG2Aeiq6PVxxEeIO+w/VBCuAgpGTFV2N/ZIF8VfjFNdWiN5OGLWQNHC2KGj2G2uV +fA+B91txQWtjY9h72YJb2+aGIixcnLY24ni4mDgDItqtpCB4PW56W8cbnbv9Pl+ aXAWdADqJdDyllHoVB/JQ24gr2fATJGRIDeYDnw+vPP4f5ZT5vg= =f00t -----END PGP SIGNATURE----- Merge tag 'f2fs-for-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've added two features: F2FS_IOC_START_ATOMIC_REPLACE and a per-block age-based extent cache.

own objects, build own object hierarchies and use the building
blocks to build own data structures flexibly, for example, linked
lists in BPF.
- Make cgroup local storage available to non-cgroup attached BPF
programs.
- Avoid unnecessary deadlock detection and failures wrt BPF task
storage helpers.

complete header processing and crypto offloading.
- IPSec: extended ack support for more descriptive XFRM error
reporting.
- RXRPC: increase SACK table size and move processing into a
per-local endpoint kernel thread, reducing considerably the

A pile of clk driver updates with a small tracepoint patch to the clk core this
time around. The core framework is effectively unchanged, with the majority of
the diff going to the Qualcomm clk driver directory because they added two 3k
line files that are almost all clk data (Abel Vesa from Linaro tried to shrink
the number of lines down, but it doesn't seem to be possible without
sacrificing readability). The second big driver this time around is the
Rockchip rk3588 clk and reset unit, at _only_ 2.5k lines.
Ignoring the big clk drivers from the familiar SoC vendors, there's just a
bunch of little clk driver updates and fixes throughout here. It's the usual
set of clk data fixups to describe proper parents, or add frequencies to
frequency tables, or plug memory leaks when function calls fail. Also, some
drivers are converted to use modern clk_hw APIs, which is always nice to see.
And data is deduplicated, leading to a smaller kernel Image. Overall this batch
has a larger collection of cleanups than it typically does. Maybe that means
there are less new SoCs right now that need supporting, and the focus has
shifted to quality and reliability. I can dream.
New Drivers:
- Frequency hopping controller hardware on MediaTek MT8186
- Global clock controller for Qualcomm SM8550
- Display clock controller for Qualcomm SC8280XP
- RPMh clock controller for Qualcomm QDU1000 and QRU1000 SoCs
- CPU PLL on MStar/SigmaStar SoCs
- Support for the clock and reset unit of the Rockchip rk3588
Updates:
- Tracepoints for clk_rate_request structures
- Debugfs support for fractional divider clk
- Make MxL's CGU driver secure compatible
- Ingenic JZ4755 SoC clk support
- Support audio clks on X1000 SoCs
- Remove flags from univ/main/syspll child fixed factor clocks across
MediaTek platforms
- Fix clock dependency for ADC on MediaTek MT7986
- Fix parent for FlexSPI clock for i.MX93
- Add USB suspend clock on i.MX8MP
- Unmap anatop base on error for i.MX93 driver
- Change enet clock parent to wakeup_axi_root for i.MX93

tracing: Remove pointer (asterisk) and brackets from cpumask_t field
To differentiate between long arrays and cpumasks, the __cpumask() field
was created. Part of the TRACE_EVENT() macros test if the type is signed
or not by using the is_signed_type() macro. The __cpumask() field used the
__dynamic_array() helper but because cpumask_t is a structure, it could
not be used in the is_signed_type() macro as that would fail to build, so
instead it passed in the pointer to cpumask_t.
Unfortunately, that creates in the format file:
field:__data_loc cpumask_t *[] mask; offset:36; size:4; signed:0;
Which looks like an array of pointers to cpumask_t and not a cpumask_t
type, which is misleading to user space parsers.
Douglas Raillard pointed out that the "[]" are also misleading, as
cpumask_t is not an array.
Since cpumask() hasn't been created yet, and the parsers currently fail on
it (but will still produce the raw output), make it be:
field:__data_loc cpumask_t mask; offset:36; size:4; signed:0;
Which is the correct type of the field.
Then the parsers can be updated to handle this.

NFSD 6.2 Release Notes
This release introduces support for the CB_RECALL_ANY operation.
NFSD can send this operation to request that clients return any
delegations they choose. The server uses this operation to handle
low memory scenarios or indicate to a client when that client has
reached the maximum number of delegations the server supports.
The NFSv4.2 READ_PLUS operation has been simplified temporarily
whilst support for sparse files in local filesystems and the VFS is
improved.
Two major data structure fixes appear in this release:
* The nfs4_file hash table is replaced with a resizable hash table
to reduce the latency of NFSv4 OPEN operations.
* Reference counting in the NFSD filecache has been hardened against
races.
In furtherance of removing support for NFSv2 in a subsequent kernel
release, a new Kconfig option enables server-side support for NFSv2
to be left out of a kernel build.
MAINTAINERS has been updated to indicate that changes to fs/exportfs
should go through the NFSD tree.

Pull btrfs updates from David Sterba:
"This round there are a lot of cleanups and moved code so the diffstat
looks huge, otherwise there are some nice performance improvements and
an update to raid56 reliability.
User visible features:
- raid56 reliability vs performance trade off:
- fix destructive RMW for raid5 data (raid6 still needs work): do
full checksum verification for all data during RMW cycle, this
should prevent rewriting potentially corrupted data without
notice
- stripes are cached in memory which should reduce the performance
impact but still can hurt some workloads
- checksums are verified after repair again
- this is the last option without introducing additional features
(write intent bitmap, journal, another tree), the extra checksum
read/verification was supposed to be avoided by the original
implementation exactly for performance reasons but that caused
all the reliability problems
- discard=async by default for devices that support it
- implement emergency flush reserve to avoid almost all unnecessary
transaction aborts due to ENOSPC in cases where there are too many
delayed refs or delayed allocation
- skip block group synchronization if there's no change in used
bytes, can reduce transaction commit count for some workloads
Performance improvements:
- fiemap and lseek:
- overall speedup due to skipping unnecessary or duplicate
searches (-40% run time)
- cache some data structures and sharedness of extents (-30% run
time)
- send:
- faster backref resolution when finding clones
- cached leaf to root mapping for faster backref walking
- improved clone/sharing detection
- overall run time improvements (-70%)
Core:
- module initialization converted to a table of function pointers run
in a sequence
- preparation for fscrypt, extend passing file names across calls,
dir item can store encryption status
- raid56 updates:
- more accurate error tracking of sectors within stripe
- simplify recovery path and remove dedicated endio worker kthread
- simplify scrub call paths
- refactoring to support the extra data checksum verification
during RMW cycle
- tree block parentness checks consolidated and done at metadata read
time
- improved error handling
- cleanups:
- move a lot of code for better synchronization between kernel and
user space sources, split big files
- enum cleanups
- GFP flag cleanups
- header file cleanups, prototypes, dependencies
- redundant parameter cleanups
- inline extent handling simplifications
- inode parameter conversion
- data structure cleanups, reductions, renames, merges"

dlm for 6.2
These patches include the usual cleanups and minor fixes, the removal of
code that is no longer needed due to recent improvements, and
improvements to processing large volumes of messages during heavy
locking activity.
- Misc code cleanup.
- Fix a couple socket handling bugs: a double release on an error path
and a data-ready race in an accept loop.
- Remove code for resending dir-remove messages. This code is no longer
needed since the midcomms layer now ensures the messages are resent if
needed.
- Add tracepoints for dlm messages.
- Improve callback queueing by replacing the fixed array with a list.
- Simplify the handling of a remove message followed by a lookup
message by sending both without releasing a spinlock in between.
- Improve the concurrency of sending and receiving messages by holding
locks for a shorter time, and changing how workqueues are used.
- Remove old code for shutting down sockets, which is no longer needed
with the reliable connection handling that was recently added.

f2fs: add block_age-based extent cache
This patch introduces a runtime hot/cold data separation method for f2fs, in order to improve the accuracy for data temperature classification, reduce the garbage collection overhead after long-term data updates. Enhanced hot/cold data separation can record data block update frequency as "age" of the extent per inode, and take use of the age info to indicate better temperature type for data block allocation: - It records total data blocks allocated since mount; - When file extent has been updated, it calculate the count of data blocks allocated since last update as the age of the extent; - Before the data block allocated, it searches for the age info and chooses the suitable segment for allocation. Test and result: - Prepare: create about 30000 files * 3% for cold files (with cold file extension like .apk, from 3M to 10M) * 50% for warm files (with random file extension like .FcDxq, from 1K to 4M) * 47% for hot files (with hot file extension like .db, from 1K to 256K) - create(5%)/random update(90%)/delete(5%) the files * total write amount is about 70G * fsync will be called for .db files, and buffered write will be used for other files The storage of test device is large enough(128G) so that it will not switch to SSR mode during the test. Benefit: dirty segment count increment reduce about 14% - before: Dirty +21110 - after: Dirty +18286 Signed-off-by: qixiaoyu1 <qixiaoyu1@xiaomi.com> Signed-off-by: xiongping1 <xiongping1@xiaomi.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> |

Merge tag 'cxl-for-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull cxl updates from Dan Williams:
"Compute Express Link (CXL) updates for 6.2.
While it may seem backwards, the CXL update this time around includes
some focus on CXL 1.x enabling where the work to date had been with
CXL 2.0 (VH topologies) in mind.
First generation CXL can mostly be supported via BIOS, similar to DDR,
however it became clear there are use cases for OS native CXL error
handling and some CXL 3.0 endpoint features can be deployed on CXL 1.x
hosts (Restricted CXL Host (RCH) topologies). So, this update brings
RCH topologies into the Linux CXL device model.
In support of the ongoing CXL 2.0+ enabling two new core kernel
facilities are added.
One is the ability for the kernel to flag collisions between userspace
access to PCI configuration registers and kernel accesses. This is
brought on by the PCIe Data-Object-Exchange (DOE) facility, a hardware
mailbox over config-cycles.
The other is a cpu_cache_invalidate_memregion() API that maps to
wbinvd_on_all_cpus() on x86. To prevent abuse it is disabled in guest
VMs and architectures that do not support it yet. The CXL paths that
need it, dynamic memory region creation and security commands (erase /
unlock), are disabled when it is not present.
As for the CXL 2.0+ this cycle the subsystem gains support Persistent
Memory Security commands, error handling in response to PCIe AER
notifications, and support for the "XOR" host bridge interleave
algorithm.
Summary:
- Add the cpu_cache_invalidate_memregion() API for cache flushing in
response to physical memory reconfiguration, or memory-side data
invalidation from operations like secure erase or memory-device
unlock.
- Add a facility for the kernel to warn about collisions between
kernel and userspace access to PCI configuration registers
- Add support for Restricted CXL Host (RCH) topologies (formerly CXL
1.1)
- Add handling and reporting of CXL errors reported via the PCIe AER
mechanism
- Add support for CXL Persistent Memory Security commands
- Add support for the "XOR" algorithm for CXL host bridge interleave
- Rework / simplify CXL to NVDIMM interactions
- Miscellaneous cleanups and fixes"

ext4: disable fast-commit of encrypted dir operations
fast-commit of create, link, and unlink operations in encrypted
directories is completely broken because the unencrypted filenames are
being written to the fast-commit journal instead of the encrypted
filenames. These operations can't be replayed, as encryption keys
aren't present at journal replay time. It is also an information leak.
Until if/when we can get this working properly, make encrypted directory
operations ineligible for fast-commit.
Note that fast-commit operations on encrypted regular files continue to
be allowed, as they seem to work.

clk: Add trace events for rate requests
It is currently fairly difficult to follow what clk_rate_request are issued, and how they have been modified once done. Indeed, there's multiple paths that can be taken, some functions are recursive and will just forward the request to its parent, etc. Adding a lot of debug prints is just not very convenient, so let's add trace events for the clock requests, one before they are submitted and one after they are returned. That way we can simply toggle the tracing on without modifying the kernel code and without affecting performances or the kernel logs too much.

fscache: Fix oops due to race with cookie_lru and use_cookie
If a cookie expires from the LRU and the LRU_DISCARD flag is set, but
the state machine has not run yet, it's possible another thread can call
fscache_use_cookie and begin to use it.
When the cookie_worker finally runs, it will see the LRU_DISCARD flag
set, transition the cookie->state to LRU_DISCARDING, which will then
withdraw the cookie. Once the cookie is withdrawn the object is removed
the below oops will occur because the object associated with the cookie
is now NULL.
Fix the oops by clearing the LRU_DISCARD bit if another thread uses the
cookie before the cookie_worker runs.

rxrpc: Make the I/O thread take over the call and local processor work
Move the functions from the call->processor and local->processor work items into the domain of the I/O thread. The call event processor, now called from the I/O thread, then takes over the job of cranking the call state machine, processing incoming packets and transmitting DATA, ACK and ABORT packets. In a future patch, rxrpc_send_ACK() will transmit the ACK on the spot rather than queuing it for later transmission. The call event processor becomes purely received-skb driven. It only transmits things in response to events. We use "pokes" to queue a dummy skb to make it do things like start/resume transmitting data. Timer expiry also results in pokes. The connection event processor, becomes similar, though crypto events, such as dealing with CHALLENGE and RESPONSE packets is offloaded to a work item to avoid doing crypto in the I/O thread. The local event processor is removed and VERSION response packets are generated directly from the packet parser. Similarly, ABORTs generated in response to protocol errors will be transmitted immediately rather than being pushed onto a queue for later transmission.

Move DATA transmission into the call processor work item. In a future patch, this will be called from the I/O thread rather than being itsown work item. This will allow DATA transmission to be driven directly by incoming ACKs, pokes and timers as those are processed. The Tx queue is also split: The queue of packets prepared by sendmsg is now places in call->tx_sendmsg and the packet dispatcher decants the packets into call->tx_buffer as space becomes available in the transmission window. This allows sendmsg to run ahead of the available space to try and prevent an underflow in transmission.

rxrpc: Don't hold a ref for connection workqueue
Currently, rxrpc gives the connection's work item a ref on the connection
when it queues it - and this is called from the timer expiration function.
The problem comes when queue_work() fails (ie. the work item is already
queued): the timer routine must put the ref - but this may cause the
cleanup code to run.
This has the unfortunate effect that the cleanup code may then be run in
softirq context - which means that any spinlocks it might need to touch
have to be guarded to disable softirqs (ie. they need a "_bh" suffix).
(1) Don't give a ref to the work item.
(2) Simplify handling of service connections by adding a separate active
count so that the refcount isn't also used for this.
(3) Connection destruction for both client and service connections can
then be cleaned up by putting rxrpc_put_connection() out of line and
making a tidy progression through the destruction code (offloaded to a
workqueue if put from softirq or processor function context). The RCU
part of the cleanup then only deals with the freeing at the end.
(4) Make rxrpc_queue_conn() return immediately if it sees the active count
is -1 rather then queuing the connection.
(5) Make sure that the cleanup routine waits for the work item to
complete.
(6) Stash the rxrpc_net pointer in the conn struct so that the rcu free
routine can use it, even if the local endpoint has been freed.
Unfortunately, neither the timer nor the work item can simply get around
the problem by just using refcount_inc_not_zero() as the waits would still
have to be done, and there would still be the possibility of having to put
the ref in the expiration function.
Note the connection work item is mostly going to go away with the main
event work being transferred to the I/O thread, so the wait in (6) will
become obsolete.

rxrpc: Don't hold a ref for call timer or workqueue
Currently, rxrpc gives the call timer a ref on the call when it starts it
and this is passed along to the workqueue by the timer expiration function.
The problem comes when queue_work() fails (ie. the work item is already
queued): the timer routine must put the ref - but this may cause the
cleanup code to run.
This has the unfortunate effect that the cleanup code may then be run in
softirq context - which means that any spinlocks it might need to touch
have to be guarded to disable softirqs (ie. they need a "_bh" suffix).
Fix this by:
(1) Don't give a ref to the timer.
(2) Making the expiration function not do anything if the refcount is 0.
Note that this is more of an optimisation.
(3) Make sure that the cleanup routine waits for timer to complete.
However, this has a consequence that timer cannot give a ref to the work
item. Therefore the following fixes are also necessary:
(4) Don't give a ref to the work item.
(5) Make the work item return asap if it sees the ref count is 0.
(6) Make sure that the cleanup routine waits for the work item to
complete.
Unfortunately, neither the timer nor the work item can simply get around
the problem by just using refcount_inc_not_zero() as the waits would still
have to be done, and there would still be the possibility of having to put
the ref in the expiration function.
Note the call work item is going to go away with the work being transferred
to the I/O thread, so the wait in (6) will become obsolete.

mm: convert mm's rss stats into percpu_counter
Currently mm_struct maintains rss_stats which are updated on page fault and the unmapping codepaths. For page fault codepath the updates are cached per thread with the batch of TASK_RSS_EVENTS_THRESH which is 64. The reason for caching is performance for multithreaded applications otherwise the rss_stats updates may become hotspot for such applications. However this optimization comes with the cost of error margin in the rss stats. The rss_stats for applications with large number of threads can be very skewed. At worst the error margin is (nr_threads * 64) and we have a lot of applications with 100s of threads, so the error margin can be very high. Internally we had to reduce TASK_RSS_EVENTS_THRESH to 32. Recently we started seeing the unbounded errors for rss_stats for specific applications which use TCP rx0cp. It seems like vm_insert_pages() codepath does not sync rss_stats at all. This patch converts the rss_stats into percpu_counter to convert the error margin from (nr_threads * 64) to approximately (nr_cpus ^ 2). However this conversion enable us to get the accurate stats for situations where accuracy is more important than the cpu cost. This patch does not make such tradeoffs - we can just use percpu_counter_add_local() for the updates and percpu_counter_sum() (or percpu_counter_sync() + percpu_counter_read) for the readers. At the moment the readers are either procfs interface, oom_killer and memory reclaim which I think are not performance critical and should be ok with slow read. However I think we can make that change in a separate patch.

tracing: Add __cpumask to denote a trace event field that is a cpumask_t
The trace events have a __bitmask field that can be used for anything that requires bitmasks. Although currently it is only used for CPU masks, it could be used in the future for any type of bitmasks. There is some user space tooling that wants to know if a field is a CPU mask and not just some random unsigned long bitmask. Introduce "__cpumask()" helper functions that work the same as the current __bitmask() helpers but displays in the format file: field:__data_loc cpumask_t *[] mask; offset:36; size:4; signed:0; Instead of: field:__data_loc unsigned long[] mask; offset:32; size:4; signed:0; The main difference is the type. Instead of "unsigned long" it is "cpumask_t *". Note, this type field needs to be a real type in the __dynamic_array() logic that both __cpumask and__bitmask use, but the comparison field requires it to be a scalar type whereas cpumask_t is a structure (non-scalar). But everything works when making it a pointer. Valentin added changes to remove the need of passing in "nr_bits" and the __cpumask will always use nr_cpumask_bits as its size.

asm-generic/io: Add _RET_IP_ to MMIO trace for more accurate debug info
Due to compiler optimizations like inlining, there are cases where
MMIO traces using _THIS_IP_ for caller information might not be
sufficient to provide accurate debug traces.
1) With optimizations (Seen with GCC):
In this case, _THIS_IP_ works fine and prints the caller information
since it will be inlined into the caller and we get the debug traces
on who made the MMIO access, for ex:
rwmmio_read: qcom_smmu_tlb_sync+0xe0/0x1b0 width=32 addr=0xffff8000087447f4
rwmmio_post_read: qcom_smmu_tlb_sync+0xe0/0x1b0 width=32 val=0x0 addr=0xffff8000087447f4
2) Without optimizations (Seen with Clang):
_THIS_IP_ will not be sufficient in this case as it will print only
the MMIO accessors itself which is of not much use since it is not
inlined as below for example:
rwmmio_read: readl+0x4/0x80 width=32 addr=0xffff8000087447f4
rwmmio_post_read: readl+0x48/0x80 width=32 val=0x4 addr=0xffff8000087447f4
So in order to handle this second case as well irrespective of the compiler
optimizations, add _RET_IP_ to MMIO trace to make it provide more accurate
debug information in all these scenarios.
Before:
rwmmio_read: readl+0x4/0x80 width=32 addr=0xffff8000087447f4
rwmmio_post_read: readl+0x48/0x80 width=32 val=0x4 addr=0xffff8000087447f4
After:
rwmmio_read: qcom_smmu_tlb_sync+0xe0/0x1b0 -> readl+0x4/0x80 width=32 addr=0xffff8000087447f4
rwmmio_post_read: qcom_smmu_tlb_sync+0xe0/0x1b0 -> readl+0x4/0x80 width=32 val=0x0 addr=0xffff8000087447f4

fs: dlm: add dst nodeid for msg tracing
In DLM when we send a dlm message it is easy to add the lock resource name, but additional lookup is required when to trace the receive message side. The idea here is to move the lookup work to the user by using a lookup to find the right send message with recv message. As note DLM can't drop any message which is guaranteed by a special session layer. For doing the lookup a 3 tupel is required as an unique identification which is dst nodeid, src nodeid and sequence number. This patch adds the destination nodeid to the dlm message trace points. The source nodeid is given by the h_nodeid field inside the header. Signed-off-by: Alexander Aring <aahringo@redhat.com> Signed-off-by: David Teigland <teigland@redhat.com> |

This patch adds tracepoints for send and recv cases of dlm messages and dlm rcom messages. In case of send and dlm message we add the dlm rsb resource name this dlm messages belongs to. This has the advantage to follow dlm messages on a per lock basis. In case of recv message the resource name can be extracted by follow the send message sequence number. The dlm message DLM_MSG_PURGE doesn't belong to a lock request and will not set the resource name in a dlm_message trace. The same for all rcom messages. There is additional handling required for this debugging functionality which is tried to be small as possible. Also the midcomms layer gets aware of lock resource names, for now this is required to make a connection between sequence number and lock resource names. It is for debugging purpose only.

rxrpc: Fix congestion management
rxrpc has a problem in its congestion management in that it saves the
congestion window size (cwnd) from one call to another, but if this is 0 at
the time is saved, then the next call may not actually manage to ever
transmit anything.
To this end:
(1) Don't save cwnd between calls, but rather reset back down to the
initial cwnd and re-enter slow-start if data transmission is idle for
more than an RTT.
(2) Preserve ssthresh instead, as that is a handy estimate of pipe
capacity. Knowing roughly when to stop slow start and enter
congestion avoidance can reduce the tendency to overshoot and drop
larger amounts of packets when probing.
In future, cwind growth also needs to be constrained when the window isn't
being filled due to being application limited.

rxrpc: Save last ACK's SACK table rather than marking txbufs
Improve the tracking of which packets need to be transmitted by saving the last ACK packet that we receive that has a populated soft-ACK table rather than marking packets. Then we can step through the soft-ACK table and look at the packets we've transmitted beyond that to determine which packets we might want to retransmit. We also look at the highest serial number that has been acked to try and guess which packets we've transmitted the peer is likely to have seen. If necessary, we send a ping to retrieve that number. One downside that might be a problem is that we can't then compare the previous acked/unacked state so easily in rxrpc_input_soft_acks() - which is a potential problem for the slow-start algorithm.

rxrpc: Don't use a ring buffer for call Tx queue
Change the way the Tx queueing works to make the following ends easier to
achieve:
(1) The filling of packets, the encryption of packets and the transmission
of packets can be handled in parallel by separate threads, rather than
rxrpc_sendmsg() allocating, filling, encrypting and transmitting each
packet before moving onto the next one.
(2) Get rid of the fixed-size ring which sets a hard limit on the number
of packets that can be retained in the ring. This allows the number
of packets to increase without having to allocate a very large ring or
having variable-sized rings.
[Note: the downside of this is that it's then less efficient to locate
a packet for retransmission as we then have to step through a list and
examine each buffer in the list.]
(3) Allow the filler/encrypter to run ahead of the transmission window.
(4) Make it easier to do zero copy UDP from the packet buffers.
(5) Make it easier to do zero copy from userspace to the packet buffers -
and thence to UDP (only if for unauthenticated connections).
To that end, the following changes are made:
(1) Use the new rxrpc_txbuf struct instead of sk_buff for keeping packets
to be transmitted in. This allows them to be placed on multiple
queues simultaneously. An sk_buff isn't really necessary as it's
never passed on to lower-level networking code.
(2) Keep the transmissable packets in a linked list on the call struct
rather than in a ring. As a consequence, the annotation buffer isn't
used either; rather a flag is set on the packet to indicate ackedness.
(3) Use the RXRPC_CALL_TX_LAST flag to indicate that the last packet to be
transmitted has been queued. Add RXRPC_CALL_TX_ALL_ACKED to indicate
that all packets up to and including the last got hard acked.
(4) Wire headers are now stored in the txbuf rather than being concocted
on the stack and they're stored immediately before the data, thereby
allowing zerocopy of a single span.
(5) Don't bother with instant-resend on transmission failure; rather,
leave it for a timer or an ACK packet to trigger.

rxrpc: Get rid of the Rx ring
Get rid of the Rx ring and replace it with a pair of queues instead. One queue gets the packets that are in-sequence and are ready for processing by recvmsg(); the other queue gets the out-of-sequence packets for addition to the first queue as the holes get filled. The annotation ring is removed and replaced with a SACK table. The SACK table has the bits set that correspond exactly to the sequence number of the packet being acked. The SACK ring is copied when an ACK packet is being assembled and rotated so that the first ACK is in byte 0. Flow control handling is altered so that packets that are moved to the in-sequence queue are hard-ACK'd even before they're consumed - and then the Rx window size in the ACK packet (rsize) is shrunk down to compensate (even going to 0 if the window is full).

rxrpc: Clone received jumbo subpackets and queue separately
Split up received jumbo packets into separate skbuffs by cloning the original skbuff for each subpacket and setting the offset and length of the data in that subpacket in the skbuff's private data. The subpackets are then placed on the recvmsg queue separately. The security class then gets to revise the offset and length to remove its metadata. If we fail to clone a packet, we just drop it and let the peer resend it. The original packet gets used for the final subpacket. This should make it easier to handle parallel decryption of the subpackets. It also simplifies the handling of lost or misordered packets in the queuing/buffering loop as the possibility of overlapping jumbo packets no longer needs to be considered.

Also, because there's a delay between an ACK being generated and being transmitted, it's possible that other ACKs of the same type will be generated during that interval. Apart from the ACK time and the serial number responded to, most of the ACK body, including window and SACK parameters, are not filled out till the point of transmission - so we can avoid generating a new ACK if there's one pending that will cover the SACK data we need to convey. Therefore, don't propose a new DELAY or IDLE ACK for a call if there's one already pending.

Pull slab fixes from Vlastimil Babka:
- The "common kmalloc v4" series [1] by Hyeonggon Yoo.
While the plan after LPC is to try again if it's possible to get rid
of SLOB and SLAB (and if any critical aspect of those is not possible
to achieve with SLUB today, modify it accordingly), it will take a
while even in case there are no objections.
Meanwhile this is a nice cleanup and some parts (e.g. to the
tracepoints) will be useful even if we end up with a single slab
implementation in the future:
- Improves the mm/slab_common.c wrappers to allow deleting
duplicated code between SLAB and SLUB.
- Large kmalloc() allocations in SLAB are passed to page allocator
like in SLUB, reducing number of kmalloc caches.
- Removes the {kmem_cache_alloc,kmalloc}_node variants of
tracepoints, node id parameter added to non-_node variants.
- Addition of kmalloc_size_roundup()
The first two patches from a series by Kees Cook [2] that introduce
kmalloc_size_roundup(). This will allow merging of per-subsystem
patches using the new function and ultimately stop (ab)using ksize()
in a way that causes ongoing trouble for debugging functionality and
static checkers.
- Wasted kmalloc() memory tracking in debugfs alloc_traces
A patch from Feng Tang that enhances the existing debugfs
alloc_traces file for kmalloc caches with information about how much
space is wasted by allocations that needs less space than the
particular kmalloc cache provides.
- My series [3] to fix validation races for caches with enabled
debugging:
- By decoupling the debug cache operation more from non-debug
fastpaths, extra locking simplifications were possible and thus
done afterwards.
- Additional cleanup of PREEMPT_RT specific code on top, by Thomas
Gleixner.
- A late fix for slab page leaks caused by the series, by Feng
Tang.
- Smaller fixes and cleanups:
- Unneeded variable removals, by ye xingchen
- A cleanup removing a BUG_ON() in create_unique_id(), by Chao Yu

Pull btrfs updates from David Sterba:
"There's a bunch of performance improvements, most notably the FIEMAP
speedup, the new block group tree to speed up mount on large
filesystems, more io_uring integration, some sysfs exports and the
usual fixes and core updates.
Summary:
Performance:
- outstanding FIEMAP speed improvement
- algorithmic change how extents are enumerated leads to orders of
magnitude speed boost (uncached and cached)
- extent sharing check speedup (2.2x uncached, 3x cached)
- add more cancellation points, allowing to interrupt seeking in
files with large number of extents
- more efficient hole and data seeking (4x uncached, 1.3x cached)
- sample results:
256M, 32K extents: 4s -> 29ms (~150x)
512M, 64K extents: 30s -> 59ms (~550x)
1G, 128K extents: 225s -> 120ms (~1800x)
- improved inode logging, especially for directories (on dbench
workload throughput +25%, max latency -21%)
- improved buffered IO, remove redundant extent state tracking,
lowering memory consumption and avoiding rb tree traversal
- add sysfs tunable to let qgroup temporarily skip exact accounting
when deleting snapshot, leading to a speedup but requiring a rescan
after that, will be used by snapper
- support io_uring and buffered writes, until now it was just for
direct IO, with the no-wait semantics implemented in the buffered
write path it now works and leads to speed improvement in IOPS
(2x), throughput (2.2x), latency (depends, 2x to 150x)
- small performance improvements when dropping and searching for
extent maps as well as when flushing delalloc in COW mode
(throughput +5MB/s)
User visible changes:
- new incompatible feature block-group-tree adding a dedicated tree
for tracking block groups, this allows a much faster load during
mount and avoids seeking unlike when it's scattered in the extent
tree items
- this reduces mount time for many-terabyte sized filesystems
- conversion tool will be provided so existing filesystem can also
be updated in place
- to reduce test matrix and feature combinations requires no-holes
and free-space-tree (mkfs defaults since 5.15)
- improved reporting of super block corruption detected by scrub
- scrub also tries to repair super block and does not wait until next
commit
- discard stats and tunables are exported in sysfs
(/sys/fs/btrfs/FSID/discard)
- qgroup status is exported in sysfs
(/sys/sys/fs/btrfs/FSID/qgroups/)
- verify that super block was not modified when thawing filesystem
Fixes:
- FIEMAP fixes
- fix extent sharing status, does not depend on the cached status
where merged
- flush delalloc so compressed extents are reported correctly
- fix alignment of VMA for memory mapped files on THP
- send: fix failures when processing inodes with no links (orphan
files and directories)
- fix race between quota enable and quota rescan ioctl
- handle more corner cases for read-only compat feature verification
- fix missed extent on fsync after dropping extent maps
Core:
- lockdep annotations to validate various transactions states and
state transitions
- preliminary support for fs-verity in send
- more effective memory use in scrub for subpage where sector is
smaller than page
- block group caching progress logic has been removed, load is now
synchronous
- simplify end IO callbacks and bio handling, use chained bios
instead of own tracking
- add no-wait semantics to several functions (tree search, nocow,
flushing, buffered write
- cleanups and refactoring
MM changes:
- export balance_dirty_pages_ratelimited_flags"

Pull erofs updates from Gao Xiang:
"In this cycle, for container use cases, fscache-based shared domain is
introduced [1] so that data blobs in the same domain will be storage
deduplicated and it will also be used for page cache sharing later.
Also, a special packed inode is now introduced to record inode
fragments which keep the tail part of files by Yue Hu [2]. You can
keep arbitary length or (at will) the whole file as a fragment and
then fragments can be optionally compressed in the packed inode
together and even deduplicated for smaller image sizes.
In addition to that, global compressed data deduplication by sharing
partial-referenced pclusters is also supported in this cycle.

Add huge_memory:trace_mm_khugepaged_scan_file tracepoint to hpage_collapse_scan_file() analogously to hpage_collapse_scan_pmd(). While this change is targeted at debugging MADV_COLLAPSE pathway, the "mm_khugepaged" prefix is retained for symmetry with huge_memory:trace_mm_khugepaged_scan_pmd, which retains it's legacy name to prevent changing kernel ABI as much as possible.

mm/madvise: add file and shmem support to MADV_COLLAPSE
Add support for MADV_COLLAPSE to collapse shmem-backed and file-backed memory into THPs (requires CONFIG_READ_ONLY_THP_FOR_FS=y). On success, the backing memory will be a hugepage. For the memory range and process provided, the page tables will synchronously have a huge pmd installed, mapping the THP. Other mappings of the file extent mapped by the memory range may be added to a set of entries that khugepaged will later process and attempt update their page tables to map the THP by a pmd. This functionality unlocks two important uses: (1) Immediately back executable text by THPs. Current support provided by CONFIG_READ_ONLY_THP_FOR_FS may take a long time on a large system which might impair services from serving at their full rated load after (re)starting. Tricks like mremap(2)'ing text onto anonymous memory to immediately realize iTLB performance prevents page sharing and demand paging, both of which increase steady state memory footprint. Now, we can have the best of both worlds: Peak upfront performance and lower RAM footprints. (2) userfaultfd-based live migration of virtual machines satisfy UFFD faults by fetching native-sized pages over the network (to avoid latency of transferring an entire hugepage). However, after guest memory has been fully copied to the new host, MADV_COLLAPSE can be used to immediately increase guest performance. Since khugepaged is single threaded, this change now introduces possibility of collapse contexts racing in file collapse path. There a important few places to consider: (1) hpage_collapse_scan_file(), when we xas_pause() and drop RCU. We could have the memory collapsed out from under us, but the next xas_for_each() iteration will correctly pick up the hugepage. The hugepage might not be up to date (insofar as copying of small page contents might not have completed - the page still may be locked), but regardless what small page index we were iterating over, we'll find the hugepage and identify it as a suitably aligned compound page of order HPAGE_PMD_ORDER. In khugepaged path, we locklessly check the value of the pmd, and only add it to deferred collapse array if we find pmd mapping pte table. This is fine, since other values that could have raced in right afterwards denote failure, or that the memory was successfully collapsed, so we don't need further processing. In madvise path, we'll take mmap_lock() in write to serialize against page table updates and will know what to do based on the true value of the pmd: recheck all ptes if we point to a pte table, directly install the pmd, if the pmd has been cleared, but memory not yet faulted, or nothing at all if we find a huge pmd. It's worth putting emphasis here on how we treat the none pmd here. If khugepaged has processed this mm's page tables already, it will have left the pmd cleared (ready for refault by the process). Depending on the VMA flags and sysfs settings, amount of RAM on the machine, and the current load, could be a relatively common occurrence - and as such is one we'd like to handle successfully in MADV_COLLAPSE. When we see the none pmd in collapse_pte_mapped_thp(), we've locked mmap_lock in write and checked (a) huepaged_vma_check() to see if the backing memory is appropriate still, along with VMA sizing and appropriate hugepage alignment within the file, and (b) we've found a hugepage head of order HPAGE_PMD_ORDER at the offset in the file mapped by our hugepage-aligned virtual address. Even though the common-case is likely race with khugepaged, given these checks (regardless how we got here - we could be operating on a completely different file than originally checked in hpage_collapse_scan_file() for all we know) it should be safe to directly make the pmd a huge pmd pointing to this hugepage. (2) collapse_file() is mostly serialized on the same file extent by lock sequence: | lock hupepage | lock mapping->i_pages | lock 1st page | unlock mapping->i_pages | <page checks> | lock mapping->i_pages | page_ref_freeze(3) | xas_store(hugepage) | unlock mapping->i_pages | page_ref_unfreeze(1) | unlock 1st page V unlock hugepage Once a context (who already has their fresh hugepage locked) locks mapping->i_pages exclusively, it will hold said lock until it locks the first page, and it will hold that lock until the after the hugepage has been added to the page cache (and will unlock the hugepage after page table update, though that isn't important here). A racing context that loses the race for mapping->i_pages will then lose the race to locking the first page. Here - depending on how far the other racing context has gotten - we might find the new hugepage (in which case we'll exit cleanly when we check PageTransCompound()), or we'll find the "old" 1st small page (in which we'll exit cleanly when we discover unexpected refcount of 2 after isolate_lru_page()). This is assuming we are able to successfully lock the page we find - in shmem path, we could just fail the trylock and exit cleanly anyways. Failure path in collapse_file() is similar: once we hold lock on 1st small page, we are serialized against other collapse contexts. Before the 1st small page is unlocked, we add it back to the pagecache and unfreeze the refcount appropriately. Contexts who lost the race to the 1st small page will then find the same 1st small page with the correct refcount and will be able to proceed.

mm/khugepaged: attempt to map file/shmem-backed pte-mapped THPs by pmds
The main benefit of THPs are that they can be mapped at the pmd level, increasing the likelihood of TLB hit and spending less cycles in page table walks. pte-mapped hugepages - that is - hugepage-aligned compound pages of order HPAGE_PMD_ORDER mapped by ptes - although being contiguous in physical memory, don't have this advantage. In fact, one could argue they are detrimental to system performance overall since they occupy a precious hugepage-aligned/sized region of physical memory that could otherwise be used more effectively. Additionally, pte-mapped hugepages can be the cheapest memory to collapse for khugepaged since no new hugepage allocation or copying of memory contents is necessary - we only need to update the mapping page tables. In the anonymous collapse path, we are able to collapse pte-mapped hugepages (albeit, perhaps suboptimally), but the file/shmem path makes no effort when compound pages (of any order) are encountered. Identify pte-mapped hugepages in the file/shmem collapse path. The final step of which makes a racy check of the value of the pmd to ensure it maps a pte table. This should be fine, since races that result in false-positive (i.e. attempt collapse even though we shouldn't) will fail later in collapse_pte_mapped_thp() once we actually lock mmap_lock and reinspect the pmd value. Races that result in false-negatives (i.e. where we decide to not attempt collapse, but should have) shouldn't be an issue, since in the worst case, we do nothing - which is what we've done up to this point. We make a similar check in retract_page_tables(). If we do think we've found a pte-mapped hugepgae in khugepaged context, attempt to update page tables mapping this hugepage. Note that these collapses still count towards the /sys/kernel/mm/transparent_hugepage/khugepaged/pages_collapsed counter, and if the pte-mapped hugepage was also mapped into multiple process' address spaces, could be incremented for each page table update. Since we increment the counter when a pte-mapped hugepage is successfully added to the list of to-collapse pte-mapped THPs, it's possible that we never actually update the page table either. This is different from how file/shmem pages_collapsed accounting works today where only a successful page cache update is counted (it's also possible here that no page tables are actually changed). Though it incurs some slop, this is preferred to either not accounting for the event at all, or plumbing through data in struct mm_slot on whether to account for the collapse or not. Also note that work still needs to be done to support arbitrary compound pages, and that this should all be converted to using folios.

mm: start tracking VMAs with maple tree
Start tracking the VMAs with the new maple tree structure in parallel with the rb_tree. Add debug and trace events for maple tree operations and duplicate the rb_tree that is created on forks into the maple tree. The maple tree is added to the mm_struct including the mm_init struct, added support in required mm/mmap functions, added tracking in kernel/fork for process forking, and used to find the unmapped_area and checked against what the rbtree finds. This also moves the mmap_lock() in exit_mmap() since the oom reaper call does walk the VMAs. Otherwise lockdep will be unhappy if oom happens. When splitting a vma fails due to allocations of the maple tree nodes, the error path in __split_vma() calls new->vm_ops->close(new). The page accounting for hugetlb is actually in the close() operation, so it accounts for the removal of 1/2 of the VMA which was not adjusted. This results in a negative exit value. To avoid the negative charge, set vm_start = vm_end and vm_pgoff = 0. There is also a potential accounting issue in special mappings from insert_vm_struct() failing to allocate, so reverse the charge there in the failure scenario.

Maple Tree: add new data structure
Patch series "Introducing the Maple Tree" The maple tree is an RCU-safe range based B-tree designed to use modern processor cache efficiently. There are a number of places in the kernel that a non-overlapping range-based tree would be beneficial, especially one with a simple interface. If you use an rbtree with other data structures to improve performance or an interval tree to track non-overlapping ranges, then this is for you. The tree has a branching factor of 10 for non-leaf nodes and 16 for leaf nodes. With the increased branching factor, it is significantly shorter than the rbtree so it has fewer cache misses. The removal of the linked list between subsequent entries also reduces the cache misses and the need to pull in the previous and next VMA during many tree alterations. The first user that is covered in this patch set is the vm_area_struct, where three data structures are replaced by the maple tree: the augmented rbtree, the vma cache, and the linked list of VMAs in the mm_struct. The long term goal is to reduce or remove the mmap_lock contention. The plan is to get to the point where we use the maple tree in RCU mode. Readers will not block for writers. A single write operation will be allowed at a time. A reader re-walks if stale data is encountered. VMAs would be RCU enabled and this mode would be entered once multiple tasks are using the mm_struct. Davidlor said : Yes I like the maple tree, and at this stage I don't think we can ask for : more from this series wrt the MM - albeit there seems to still be some : folks reporting breakage. Fundamentally I see Liam's work to (re)move : complexity out of the MM (not to say that the actual maple tree is not : complex) by consolidating the three complimentary data structures very : much worth it considering performance does not take a hit. This was very : much a turn off with the range locking approach, which worst case scenario : incurred in prohibitive overhead. Also as Liam and Matthew have : mentioned, RCU opens up a lot of nice performance opportunities, and in : addition academia[1] has shown outstanding scalability of address spaces : with the foundation of replacing the locked rbtree with RCU aware trees. A similar work has been discovered in the academic press https://pdos.csail.mit.edu/papers/rcuvm:asplos12.pdf Sheer coincidence. We designed our tree with the intention of solving the hardest problem first. Upon settling on a b-tree variant and a rough outline, we researched ranged based b-trees and RCU b-trees and did find that article. So it was nice to find reassurances that we were on the right path, but our design choice of using ranges made that paper unusable for us. This patch (of 70): The maple tree is an RCU-safe range based B-tree designed to use modern processor cache efficiently. There are a number of places in the kernel that a non-overlapping range-based tree would be beneficial, especially one with a simple interface. If you use an rbtree with other data structures to improve performance or an interval tree to track non-overlapping ranges, then this is for you.

A single write operation will be allowed at a time. A reader re-walks if stale data is encountered. VMAs would be RCU enabled and this mode would be entered once multiple tasks are using the mm_struct. There is additional BUG_ON() calls added within the tree, most of which are in debug code. These will be replaced with a WARN_ON() call in the future. There is also additional BUG_ON() calls within the code which will also be reduced in number at a later date. These exist to catch things such as out-of-range accesses which would crash anyways.

btrfs: convert the io_failure_tree to a plain rb_tree
We still have this oddity of stashing the io_failure_record in the extent state for the io_failure_tree, which is leftover from when we used to stuff private pointers in extent_io_trees. However this doesn't make a lot of sense for the io failure records, we can simply use a normal rb_tree for this. This will allow us to further simplify the extent_io_tree code by removing the io_failure_rec pointer from the extent state. Convert the io_failure_tree to an rb tree + spinlock in the inode, and then use our rb tree simple helpers to insert and find failed records. This greatly cleans up this code and makes it easier to separate out the extent_io_tree code.

habanalabs: trace DMA allocations
This patch add tracepoints in the code for DMA allocation. The main purpose is to be able to cross data with the map operations and determine whether memory violation occurred, for example free DMA allocation before unmapping it from device memory. To achieve this the DMA alloc/free code flows were refactored so that a single DMA tracepoint will catch many flows. To get better understanding of what happened in the DMA allocations the real allocating function is added to the trace as well.

habanalabs: define trace events
This patch adds trace events for habanalabs driver to gain all the benefits such an infrastructure can supply. The following events were added: - MMU map/unmap: to be able to track driver's memory allocations - DMA alloc/free: to track our DMA allocation the above trace points in conjunction will help us map the device memory usage as well as to be able to track memory violations.

mm/khugepaged: record SCAN_PMD_MAPPED when scan_pmd() finds hugepage
When scanning an anon pmd to see if it's eligible for collapse, return SCAN_PMD_MAPPED if the pmd already maps a hugepage. Note that SCAN_PMD_MAPPED is different from SCAN_PAGE_COMPOUND used in the file-collapse path, since the latter might identify pte-mapped compound pages. This is required by MADV_COLLAPSE which necessarily needs to know what hugepage-aligned/sized regions are already pmd-mapped. In order to determine if a pmd already maps a hugepage, refactor mm_find_pmd(): Return mm_find_pmd() to it's pre-commit |

net: skb: export skb drop reaons to user by TRACE_DEFINE_ENUM
As Eric reported, the 'reason' field is not presented when trace the kfree_skb event by perf: $ perf record -e skb:kfree_skb -a sleep 10 $ perf script ip_defrag 14605 [021] 221.614303: skb:kfree_skb: skbaddr=0xffff9d2851242700 protocol=34525 location=0xffffffffa39346b1 reason: The cause seems to be passing kernel address directly to TP_printk(), which is not right. As the enum 'skb_drop_reason' is not exported to user space through TRACE_DEFINE_ENUM(), perf can't get the drop reason string from the 'reason' field, which is a number. Therefore, we introduce the macro DEFINE_DROP_REASON(), which is used to define the trace enum by TRACE_DEFINE_ENUM(). With the help of DEFINE_DROP_REASON(), now we can remove the auto-generate that we introduced in the commit |

mm/slab_common: drop kmem_alloc & avoid dereferencing fields when not using
Drop kmem_alloc event class, and define kmalloc and kmem_cache_alloc
using TRACE_EVENT() macro.
And then this patch does:
- Do not pass pointer to struct kmem_cache to trace_kmalloc.
gfp flag is enough to know if it's accounted or not.
- Avoid dereferencing s->object_size and s->size when not using kmem_cache_alloc event.
- Avoid dereferencing s->name in when not using kmem_cache_free event.
- Adjust s->size to SLOB_UNITS(s->size) * SLOB_UNIT in SLOB

mm/slab_common: unify NUMA and UMA version of tracepoints
Drop kmem_alloc event class, rename kmem_alloc_node to kmem_alloc, and
remove _node postfix for NUMA version of tracepoints.
This will break some tools that depend on {kmem_cache_alloc,kmalloc}_node,
but at this point maintaining both kmem_alloc and kmem_alloc_node
event classes does not makes sense at all.

This patch adds trace callbacks for user locks. Unfortenately user locks are handled in a different way than kernel locks in some cases. User locks never call the dlm_lock()/dlm_unlock() kernel API and use the next step internal API of dlm.

firmware: arm_scmi: Harmonize SCMI tracing message format
After the recently added new scmi_msg_dump traces, the general format of the various other SCMI traces are not consistent. As an example the full traces of a simple PERF_LEVEL_SET: | cpufreq-set-276 scmi_xfer_begin: transfer_id=145 msg_id=7 protocol_id=19 seq=145 poll=0 | cpufreq-set-276 scmi_msg_dump: pt=13 t=CMND msg_id=07 seq=0091 s=0 pyld=000000008066ab13 | cpufreq-set-276 scmi_xfer_response_wait: transfer_id=145 msg_id=7 protocol_id=19 seq=145 tmo_ms=5000 poll=0 | <idle>-0 scmi_msg_dump: pt=13 t=RESP msg_id=07 seq=0091 s=0 pyld= | <idle>-0 scmi_rx_done: transfer_id=145 msg_id=7 protocol_id=19 seq=145 msg_type=0 | cpufreq-set-276 scmi_xfer_end: transfer_id=145 msg_id=7 protocol_id=19 seq=145 status=0 ... where the same information is being reported using different names (protocol_id= vs pt=) and even worst different bases, which is hard to read and to parse. So let us unify them, using the same naming and ordering of the fields (wherever possible) and moving all the protocol related fields to base-16 while keeping in base-10 timeouts, res_id and values, so that the new traces would be like: | cpufreq-set-274 scmi_xfer_begin: pt=13 msg_id=07 seq=0092 transfer_id=92 poll=0 | cpufreq-set-274 scmi_msg_dump: pt=13 t=CMND msg_id=07 seq=0092 s=0 pyld=000000008066ab13 | cpufreq-set-274 scmi_xfer_response_wait: pt=13 msg_id=07 seq=0092 transfer_id=92 tmo_ms=5000 poll=0 | cat-256 scmi_msg_dump: pt=13 t=RESP msg_id=07 seq=0092 s=0 pyld= | cat-256 scmi_rx_done: pt=13 msg_id=07 seq=0092 transfer_id=92 msg_type=0 | cpufreq-set-274 scmi_xfer_end: pt=13 msg_id=07 seq=0092 transfer_id=92 s=0 Link: https://lore.kernel.org/r/20220818132309.584042-2-cristian.marussi@arm.com Signed-off-by: Cristian Marussi <cristian.marussi@arm.com> Signed-off-by: Sudeep Holla <sudeep.holla@arm.com> |

KVM: x86/mmu: rename trace function name for asynchronous page fault
Rename the tracepoint function from trace_kvm_async_pf_doublefault() to trace_kvm_async_pf_repeated_fault() to make it clear, since double fault has nothing to do with this trace function. Asynchronous Page Fault (APF) is an artifact generated by KVM when it cannot find a physical page to satisfy an EPT violation. KVM uses APF to tell the guest OS to do something else such as scheduling other guest processes to make forward progress. However, when another guest process also touches a previously APFed page, KVM halts the vCPU instead of generating a repeated APF to avoid wasting cycles. Double fault (#DF) clearly has a different meaning and a different consequence when triggered. #DF requires two nested contributory exceptions instead of two page faults faulting at the same address. A prevous bug on APF indicates that it may trigger a double fault in the guest [1] and clearly this trace function has nothing to do with it. So rename this function should be a valid choice. No functional change intended.

NFSD 6.0 Release Notes
Work on "courteous server", which was introduced in 5.19, continues apace. This release introduces a more flexible limit on the number of NFSv4 clients that NFSD allows, now that NFSv4 clients can remain in courtesy state long after the lease expiration timeout. The client limit is adjusted based on the physical memory size of the server. The NFSD filecache is a cache of files held open by NFSv4 clients or recently touched by NFSv2 or NFSv3 clients. This cache had some significant scalability constraints that have been relieved in this release. Thanks to all who contributed to this work. A data corruption bug found during the most recent NFS bake-a-thon that involves NFSv3 and NFSv4 clients writing the same file has been addressed in this release. This release includes several improvements in CPU scalability for NFSv4 operations. In addition, Neil Brown provided patches that simplify locking during file lookup, creation, rename, and removal that enables subsequent work on making these operations more scalable. We expect to see that work materialize in the next release. There are also numerous single-patch fixes, clean-ups, and the usual improvements in observability. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmLujF0ACgkQM2qzM29m f5c14w/+Lsoryo5vdTXMAZBXBNvVdXQmHqLIEotJEVA3sECr+Kad2bF8rFaCWVzS Gf9KhTetmcDO9O73I5I/UtJ2qFT9B4I6baSGpOzIkjsM/aKeEEQpbpdzPYhKrCEv bQu3P54js7snH4YV8s0I39nBFOWdnahYXaw7peqE/2GOHxaR2mz88bkrQ+OybCxz KETqUxA6bKzkOT61S0nHcnQKd8HQzhocMDtrxtANHGsMM167ngI1dw4tUQAtfAUI s9R+GS6qwiKgwGz1oqhTR6LA/h4DROxPnc7AieuD9FvuAnR3kXw61bGMN5Biwv2T JZUTBbQvWhNasSV+7qOY9nBu+sHVC6Q7OZ5C9F/KjMyqCioDX0DnbxX9uKP20CDd EAAMS8n4Tdgd4KRBWdkLXPzizWYAjZQmFIJtcZne1JzGZ4IWRnikgM5qD6n1VviZ kcPRm5EN3DRHA+Hte4jG0EHIrE/7g5gnf+zr9dWl3uNhZtfTmumCfU16YYmKG8pP QN4kXBR2w7dAvp8nRaOsY6bBFLDAk/jHbpY8Q4xoUO4tsojfWayCTGVFOrecOjxv uSn0LhiidC5pLlkcPgwemhysVywDzr+gGXBRJXeUOHfdd05Q2gbFK8OpqDSvJ3dZ aC/RxFvHc8jaktUcuIjkE6Rsz6AVaAH3EZj84oMZ4hZhyGbEreg= =PEJ3 -----END PGP SIGNATURE----- Merge tag 'nfsd-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "Work on 'courteous server', which was introduced in 5.19, continues apace.

IOMMU Updates for Linux v5.20/v6.0:
Including:
- Most intrusive patch is small and changes the default
allocation policy for DMA addresses. Before the change the
allocator tried its best to find an address in the first 4GB.
But that lead to performance problems when that space gets
exhaused, and since most devices are capable of 64-bit DMA
these days, we changed it to search in the full DMA-mask
range from the beginning. This change has the potential to
uncover bugs elsewhere, in the kernel or the hardware. There
is a Kconfig option and a command line option to restore the
old behavior, but none of them is enabled by default.
- Add Robin Murphy as reviewer of IOMMU code and maintainer for
the dma-iommu and iova code
- Chaning IOVA magazine size from 1032 to 1024 bytes to save
memory
- Some core code cleanups and dead-code removal
- Support for ACPI IORT RMR node
- Support for multiple PCI domains in the AMD-Vi driver
- ARM SMMU changes from Will Deacon:
- Add even more Qualcomm device-tree compatible strings
- Support dumping of IMP DEF Qualcomm registers on TLB sync
timeout
- Fix reference count leak on device tree node in Qualcomm
driver
- Intel VT-d driver updates from Lu Baolu:
- Make intel-iommu.h private
- Optimize the use of two locks
- Extend the driver to support large-scale platforms
- Cleanup some dead code
- MediaTek IOMMU refactoring and support for TTBR up to 35bit
- Basic support for Exynos SysMMU v7
- VirtIO IOMMU driver gets a map/unmap_pages() implementation
- Other smaller cleanups and fixes

asm-generic: updates for 6.0
There are three independent sets of changes:
- Sai Prakash Ranjan adds tracing support to the asm-generic
version of the MMIO accessors, which is intended to help
understand problems with device drivers and has been part
of Qualcomm's vendor kernels for many years.
- A patch from Sebastian Siewior to rework the handling of
IRQ stacks in softirqs across architectures, which is
needed for enabling PREEMPT_RT.
- The last patch to remove the CONFIG_VIRT_TO_BUS option and
some of the code behind that, after the last users of this
old interface made it in through the netdev, scsi, media and
staging trees.

Tracing updates for 5.20 / 6.0
- Runtime verification infrastructure
This is the biggest change for this pull request. It introduces the
runtime verification that is necessary for running Linux on safety
critical systems. It allows for deterministic automata models to be
inserted into the kernel that will attach to tracepoints, where the
information on these tracepoints will move the model from state to state.
If a state is encountered that does not belong to the model, it will then
activate a given reactor, that could just inform the user or even panic
the kernel (for which safety critical systems will detect and can recover
from).
- Two monitor models are also added: Wakeup In Preemptive (WIP - not to be
confused with "work in progress"), and Wakeup While Not Running (WWNR).
- Added __vstring() helper to the TRACE_EVENT() macro to replace several
vsnprintf() usages that were all doing it wrong.
- eprobes now can have their event autogenerated when the event name is left
off.
- The rest is various cleanups and fixes.

Pull btrfs updates from David Sterba:
"This brings some long awaited changes, the send protocol bump,
otherwise lots of small improvements and fixes. The main core part is
reworking bio handling, cleaning up the submission and endio and
improving error handling.
There are some changes outside of btrfs adding helpers or updating
API, listed at the end of the changelog.
Features:
- sysfs:
- export chunk size, in debug mode add tunable for setting its size
- show zoned among features (was only in debug mode)
- show commit stats (number, last/max/total duration)
- send protocol updated to 2
- new commands:
- ability write larger data chunks than 64K
- send raw compressed extents (uses the encoded data ioctls),
ie. no decompression on send side, no compression needed on
receive side if supported
- send 'otime' (inode creation time) among other timestamps
- send file attributes (a.k.a file flags and xflags)
- this is first version bump, backward compatibility on send and
receive side is provided
- there are still some known and wanted commands that will be
implemented in the near future, another version bump will be
needed, however we want to minimize that to avoid causing
usability issues
- print checksum type and implementation at mount time
- don't print some messages at mount (mentioned as people asked about
it), we want to print messages namely for new features so let's
make some space for that
- big metadata - this has been supported for a long time and is
not a feature that's worth mentioning
- skinny metadata - same reason, set by default by mkfs
Performance improvements:
- reduced amount of reserved metadata for delayed items
- when inserted items can be batched into one leaf
- when deleting batched directory index items
- when deleting delayed items used for deletion
- overall improved count of files/sec, decreased subvolume lock
contention
- metadata item access bounds checker micro-optimized, with a few
percent of improved runtime for metadata-heavy operations
- increase direct io limit for read to 256 sectors, improved
throughput by 3x on sample workload
Notable fixes:
- raid56
- reduce parity writes, skip sectors of stripe when there are no
data updates
- restore reading from on-disk data instead of using stripe cache,
this reduces chances to damage correct data due to RMW cycle
- refuse to replay log with unknown incompat read-only feature bit
set
- zoned
- fix page locking when COW fails in the middle of allocation
- improved tracking of active zones, ZNS drives may limit the
number and there are ENOSPC errors due to that limit and not
actual lack of space
- adjust maximum extent size for zone append so it does not cause
late ENOSPC due to underreservation
- mirror reading error messages show the mirror number
- don't fallback to buffered IO for NOWAIT direct IO writes, we don't
have the NOWAIT semantics for buffered io yet
- send, fix sending link commands for existing file paths when there
are deleted and created hardlinks for same files
- repair all mirrors for profiles with more than 1 copy (raid1c34)
- fix repair of compressed extents, unify where error detection and
repair happen
Core changes:
- bio completion cleanups
- don't double defer compression bios
- simplify endio workqueues
- add more data to btrfs_bio to avoid allocation for read requests
- rework bio error handling so it's same what block layer does,
the submission works and errors are consumed in endio
- when asynchronous bio offload fails fall back to synchronous
checksum calculation to avoid errors under writeback or memory
pressure
- new trace points
- raid56 events
- ordered extent operations
- super block log_root_transid deprecated (never used)
- mixed_backref and big_metadata sysfs feature files removed, they've
been default for sufficiently long time, there are no known users
and mixed_backref could be confused with mixed_groups
Non-btrfs changes, API updates:
- minor highmem API update to cover const arguments
- switch all kmap/kmap_atomic to kmap_local
- remove redundant flush_dcache_page()
- address_space_operations::writepage callback removed
- add bdev_max_segments() helper"

cpuidle: Add cpu_idle_miss trace event
Add a trace event for cpuidle to track missed (too deep or too shallow) wakeups. After each wakeup, CPUIdle already computes whether the entered state was optimal, above or below the desired one and updates the relevant counters. This patch makes it possible to trace those events in addition to just reading the counters. The patterns of types and percentages of misses across different workloads appear to be very consistent. This makes the trace event very useful for comparing the relative correctness of different CPUIdle governors for different types of workloads, or for finding the optimal governor for a given device.

This isn't very efficient, and we even have specific code in io-wq to serialize buffered writes to the same inode to avoid further inefficiencies with thread offload. This is particularly sad since most buffered writes don't block, they simply copy data to a page and dirty it. With this pull request, we can handle buffered writes a lot more effiently. If balance_dirty_pages() needs to block, we back off on writes as indicated. This improves buffered write support by 2-3x.

Move the code to io_uring/ and split it into files that either implement a specific request type, and split some code into helpers as well. The code is organized a lot better like this, and io_uring.c is now < 4K LOC (me). - Deprecate the epoll_ctl opcode. It'll still work, just trigger a warning once if used. If we don't get any complaints on this, and I don't expect any, then we can fully remove it in a future release (me). - Improve the cancel hash locking (Hao) - kbuf cleanups (Hao) - Efficiency improvements to the task_work handling (Dylan, Pavel) - Provided buffer improvements (Dylan) - Add support for recv/recvmsg multishot support. This is similar to the accept (or poll) support for have for multishot, where a single SQE can trigger everytime data is received. For applications that expect to do more than a few receives on an instantiated socket, this greatly improves efficiency (Dylan). - Efficiency improvements for poll handling (Pavel) - Poll cancelation improvements (Pavel) - Allow specifiying a range for direct descriptor allocations (Pavel) - Cleanup the cqe32 handling (Pavel) - Move io_uring types to greatly cleanup the tracing (Pavel) - Tons of great code cleanups and improvements (Pavel) - Add a way to do sync cancelations rather than through the sqe -> cqe interface, as that's a lot easier to use for some use cases (me). - Add support to IORING_OP_MSG_RING for sending direct descriptors to a different ring.

tracing: Use alignof__(struct {type b;}) instead of offsetof()
Simplify:
#define ALIGN_STRUCTFIELD(type) ((int)(offsetof(struct {char a; type b;}, b)))
with
#define ALIGN_STRUCTFIELD(type) __alignof__(struct {type b;})
Which works just the same.

trip structure from the thermal OF code as a generic structure to be
used by the different sensors when registering a thermal zone
(Daniel Lezcano).
- Make per cpufreq / devfreq cooling device ops instead of using a
global variable, fix comments and rework the trace information
(Lukasz Luba).
- Add the include/dt-bindings/thermal.h under the area covered by the
thermal maintainer in the MAINTAINERS file (Lukas Bulwahn).

thermal zone failed to initialize, the DT bindings by changing the
positive logic and adding the r8a779f0 support on the rcar3 (Wolfram
Sang).
- Convert the QCom tsens DT binding to the dtsformat format (Krzysztof
Kozlowski).
- Remove the pointless get_trend() function in the QCom, Ux500 and
tegra thermal drivers, along with the unused DROP_FULL and

macros (Daniel Lezcano).
- Fix ref_table memory leak at probe time on the k3_j72xx bandgap
(Bryan Brattlof).
- Fix array underflow in prep_lookup_table (Dan Carpenter).

(Jin Xiaoyun).
- Fix typos in comments detected on sun8i by Coccinelle (Julia
Lawall).
- Fix typos in comments on rzg2l (Biju Das).
- Remove as unnecessary call to dev_err() as the error is already
printed by the failing function on u8500 (Yang Li).
- Register the thermal zones as hwmon sensors for the Qcom thermal
sensors (Dmitry Baryshkov).
- Fix 'tmon' tool compilation issue by adding phtread.h include
(Markus Mayer).
- Fix typo in the comments for the 'tmon' tool (Slark Xiao).
- Make the thermal core use ida_alloc()/free() directly instead of
ida_simple_get()/ida_simple_remove() that have been deprecated
(keliu).

afs: Fix access after dec in put functions
Reference-putting functions should not access the object being put after decrementing the refcount unless they reduce the refcount to zero. Fix a couple of instances of this in afs by copying the information to be logged by tracepoint to local variables before doing the decrement.

tracing: Use a struct alignof to determine trace event field alignment
alignof() gives an alignment of types as they would be as standalone
variables. But alignment in structures might be different, and when
building the fields of events, the alignment must be the actual
alignment otherwise the field offsets may not match what they actually
are.
This caused trace-cmd to crash, as libtraceevent did not check if the
field offset was bigger than the event. The write_msr and read_msr
events on 32 bit had their fields incorrect, because it had a u64 field
between two ints. alignof(u64) would give 8, but the u64 field was at a
4 byte alignment.
Define a macro as:
ALIGN_STRUCTFIELD(type) ((int)(offsetof(struct {char a; type b;}, b)))
which gives the actual alignment of types in a structure.

rv/monitor: Add the wwnr monitor
Per task wakeup while not running (wwnr) monitor. This model is broken, the reason is that a task can be running in the processor without being set as RUNNABLE. Think about a task about to sleep: 1: set_current_state(TASK_UNINTERRUPTIBLE); 2: schedule(); And then imagine an IRQ happening in between the lines one and two, waking the task up. BOOM, the wakeup will happen while the task is running. Q: Why do we need this model, so? A: To test the reactors.

rv/monitor: Add the wip monitor
The wakeup in preemptive (wip) monitor verifies if the
wakeup events always take place with preemption disabled:
|
|
v
#==================#
H preemptive H <+
#==================# |
| |
| preempt_disable | preempt_enable
v |
sched_waking +------------------+ |
+--------------- | | |
| | non_preemptive | |
+--------------> | | -+
+------------------+
The wakeup event always takes place with preemption disabled because
of the scheduler synchronization. However, because the preempt_count
and its trace event are not atomic with regard to interrupts, some
inconsistencies might happen.
The documentation illustrates one of these cases.

rv/include: Add deterministic automata monitor definition via C macros
In Linux terms, the runtime verification monitors are encapsulated
inside the "RV monitor" abstraction. The "RV monitor" includes a set
of instances of the monitor (per-cpu monitor, per-task monitor, and
so on), the helper functions that glue the monitor to the system
reference model, and the trace output as a reaction for event parsing
and exceptions, as depicted below:
Linux +----- RV Monitor ----------------------------------+ Formal
Realm | | Realm
+-------------------+ +----------------+ +-----------------+
| Linux kernel | | Monitor | | Reference |
| Tracing | -> | Instance(s) | <- | Model |
| (instrumentation) | | (verification) | | (specification) |
+-------------------+ +----------------+ +-----------------+
| | |
| V |
| +----------+ |
| | Reaction | |
| +--+--+--+-+ |
| | | | |
| | | +-> trace output ? |
+------------------------|--|----------------------+
| +----> panic ?
+-------> <user-specified>
Add the rv/da_monitor.h, enabling automatic code generation for the
*Monitor Instance(s)* using C macros, and code to support it.
The benefits of the usage of macro for monitor synthesis are 3-fold as it:
- Reduces the code duplication;
- Facilitates the bug fix/improvement;
- Avoids the case of developers changing the core of the monitor code
to manipulate the model in a (let's say) non-standard way.
This initial implementation presents three different types of monitor
instances:
- DECLARE_DA_MON_GLOBAL(name, type)
- DECLARE_DA_MON_PER_CPU(name, type)
- DECLARE_DA_MON_PER_TASK(name, type)
The first declares the functions for a global deterministic automata monitor,
the second for monitors with per-cpu instances, and the third with per-task
instances.

tracing: Use a copy of the va_list for __assign_vstr()
If an instance of tracing enables the same trace event as another
instance, or the top level instance, or even perf, then the va_list passed
into some tracepoints can be used more than once.
As va_list can only be traversed once, this can cause issues:
# cat /sys/kernel/tracing/instances/qla2xxx/trace
cat-56106 [012] ..... 2419873.470098: ql_dbg_log: qla2xxx [0000:05:00.0]-1054:14: Entered (null).

# cat /sys/kernel/tracing/trace

cat-56106 [012] ..... 2419873.470100: ql_dbg_log: qla2xxx [0000:05:00.0]-1000:14: Entered qla2x00_mailbox_command.

The instance version is corrupted because the top level instance iterated
the va_list first.
Use va_copy() in the __assign_vstr() macro to make sure that each trace
event for each use case gets a fresh va_list.

drivers/thermal/cpufreq_cooling : Refactor thermal_power_cpu_get_power tracing
Simplify the thermal_power_cpu_get_power trace event by removing complicated cpumask and variable length array. Now the tools parsing trace output don't have to hassle to get this power data. The simplified format version uses 'policy->cpu'. Remove also the 'load' information completely since there is very little value of it in this trace event. To get the CPUs' load (or utilization) there are other dedicated trace hooks in the kernel. This patch also simplifies and speeds-up the main cooling code when that trace event is enabled. Rename the trace event to avoid confusion of tools which parse the trace file.

btrfs: add trace event for submitted RAID56 bio
Add tracepoint for better insight to how the RAID56 data are submitted.
The output looks like this: (trace event header and UUID skipped)
raid56_read_partial: full_stripe=389152768 devid=3 type=DATA1 offset=32768 opf=0x0 physical=323059712 len=32768
raid56_read_partial: full_stripe=389152768 devid=1 type=DATA2 offset=0 opf=0x0 physical=67174400 len=65536
raid56_write_stripe: full_stripe=389152768 devid=3 type=DATA1 offset=0 opf=0x1 physical=323026944 len=32768
raid56_write_stripe: full_stripe=389152768 devid=2 type=PQ1 offset=0 opf=0x1 physical=323026944 len=32768
The above debug output is from a 32K data write into an empty RAID56
data chunk.
Some explanation on the event output:
full_stripe: the logical bytenr of the full stripe
devid: btrfs devid
type: raid stripe type.
DATA1: the first data stripe
DATA2: the second data stripe
PQ1: the P stripe
PQ2: the Q stripe
offset: the offset inside the stripe.
opf: the bio op type
physical: the physical offset the bio is for
len: the length of the bio
The first two lines are from partial RMW read, which is reading the
remaining data stripes from disks.
The last two lines are for full stripe RMW write, which is writing the
involved two 16K stripes (one for DATA1 stripe, one for P stripe).
The stripe for DATA2 doesn't need to be written.
There are 5 types of trace events:
- raid56_read_partial
Read remaining data for regular read/write path.
- raid56_write_stripe
Write the modified stripes for regular read/write path.
- raid56_scrub_read_recover
Read remaining data for scrub recovery path.
- raid56_scrub_write_stripe
Write the modified stripes for scrub path.
- raid56_scrub_read
Read remaining data for scrub path.
Also, since the trace events are included at super.c, we have to export
needed structure definitions to 'raid56.h' and include the header in
super.c, or we're unable to access those members.

spmi: trace: fix stack-out-of-bound access in SPMI tracing functions
trace_spmi_write_begin() and trace_spmi_read_end() both call
memcpy() with a length of "len + 1". This leads to one extra

this out-of-bound memory access by using a length of "len"
instead.

tracing/events: Add __vstring() and __assign_vstr() helper macros
There's several places that open code the following logic:
TP_STRUCT__entry(__dynamic_array(char, msg, MSG_MAX)),
TP_fast_assign(vsnprintf(__get_str(msg), MSG_MAX, vaf->fmt, *vaf->va);)
To load a string created by variable array va_list.
The main issue with this approach is that "MSG_MAX" usage in the
__dynamic_array() portion. That actually just reserves the MSG_MAX in the
event, and even wastes space because there's dynamic meta data also saved
in the event to denote the offset and size of the dynamic array. It would
have been better to just use a static __array() field.
Instead, create __vstring() and __assign_vstr() that work like __string
and __assign_str() but instead of taking a destination string to copy,
take a format string and a va_list pointer and fill in the values.
It uses the helper:
#define __trace_event_vstr_len(fmt, va) \
({ \
va_list __ap; \
int __ret; \
\
va_copy(__ap, *(va)); \
__ret = vsnprintf(NULL, 0, fmt, __ap) + 1; \
va_end(__ap); \
\
min(__ret, TRACE_EVENT_STR_MAX); \
})
To figure out the length to store the string. It may be slightly slower as
it needs to run the vsnprintf() twice, but it now saves space on the ring
buffer.

neighbor: tracing: Have neigh_create event use __string()
The dev field of the neigh_create event uses __dynamic_array() with a fixed size, which defeats the purpose of __dynamic_array(). Looking at the logic, as it already uses __assign_str(), just use the same logic in __string to create the size needed. It appears that because "dev" can be NULL, it needs the check. But __string() can have the same checks as __assign_str() so use them there too.

tracing/ipv4/ipv6: Use static array for name field in fib*_lookup_table event
The fib_lookup_table and fib6_lookup_table events declare name as a dynamic_array, but also give it a fixed size, which defeats the purpose of the dynamic array, especially since the dynamic array also includes meta data in the event to specify its size. Since the size of the name is at most 16 bytes (defined by IFNAMSIZ), it is not worth spending the effort to determine the size of the string. Just use a fixed size array and copy into it. This will save 4 bytes that are used for the meta data that saves the size and position of a dynamic array, and even slightly speed up the event processing.

The trace event devlink_trap_report uses the __dynamic_array() macro to determine the size of the input_dev_name field. This is because it needs to test the dev field for NULL, and will use "NULL" if it is. But it also has the size of the dynamic array as a fixed IFNAMSIZ bytes. This defeats the purpose of the dynamic array, as this will reserve that amount of bytes on the ring buffer, and to make matters worse, it will even save that size in the event as the event expects it to be dynamic (for which it is not). Since IFNAMSIZ is just 16 bytes, just make it a static array and this will remove the meta data from the event that records the size.

fs/nilfs2: Use the enum req_op and blk_opf_t types
Improve static type checking by using the enum req_op type for variables that represent a request operation and the new blk_opf_t type for variables that represent request flags. Combine the 'mode' and 'mode_flags' arguments of nilfs_btnode_submit_block into a single argument 'opf'.

net: sock: tracing: Fix sock_exceed_buf_limit not to dereference stale pointer
The trace event sock_exceed_buf_limit saves the prot->sysctl_mem pointer
and then dereferences it in the TP_printk() portion. This is unsafe as the
TP_printk() portion is executed at the time the buffer is read. That is,
it can be seconds, minutes, days, months, even years later. If the proto
is freed, then this dereference will can also lead to a kernel crash.
Instead, save the sysctl_mem array into the ring buffer and have the
TP_printk() reference that instead. This is the proper and safe way to
read pointers in trace events.

Arm SCMI updates for v5.20
The main additions this time around are:
1. The capability to trace full SCMI message headers and payloads.
The recent unearthing of chain of old firmware issues motivated
this effort so that it is easier to trace them and debug quicker
than it took this time around in absence of such tracing.
2. SCMI System power control driver to handle platform's requests for a
graceful shutdown. Though the system power control protocol has been
around since the begining of SCMI, it lacked the timeout information
that was added in SCMI v3.1 that enables kernel to take appropriate
action within the timeout and doesn't have to rely on any other
user inputs(which was blocking factor for addition of this driver
earlier)
3. Support for SCMI Power Capping protocol that was introduced in SCMI v3.1
This protocol is intended for controlling and monitoring the power
consumption of power capping domains. The firmware also provides the
hierarchy of powercap domains by providing parent domain information.
It also contains a bug fix in the old SCPI driver addressing possible
user-after-free issues.

mm/tracing: add 'accounted' entry into output of allocation tracepoints
Slab caches marked with SLAB_ACCOUNT force accounting for every allocation from this cache even if __GFP_ACCOUNT flag is not passed. Unfortunately, at the moment this flag is not visible in ftrace output, and this makes it difficult to analyze the accounted allocations. This patch adds boolean "accounted" entry into trace output, and set it to 'true' for calls used __GFP_ACCOUNT flag and for allocations from caches marked with SLAB_ACCOUNT. Set it to 'false' if accounting is disabled in configs.

include: trace: Add SCMI fast channel tracing
All the currently defined SCMI events are meant to trace only regular SCMI transfers based on SCMI messages exchanges; SCMI transactions based on fast channels, where used, are completely invisible from the tracing point of view. Add support to trace fast channel transactions; while doing that avoid exposing full shared memory location addresses.
