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

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.

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

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.

mm/khugepaged: refactor mm_khugepaged_scan_file tracepoint to remove filename from function call
Refactor the mm_khugepaged_scan_file tracepoint to move filename
dereference to the tracepoint definition, to maintain consistency with
other tracepoints[1].

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> |

fd: dlm: trace send/recv of dlm message and rcom
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.

f2fs-for-6.1-rc1
This round looks fairly small comparing to the previous updates which includes
mostly minor bug fixes. Nevertheless, as we've still interested in improving
the stability, Chao added some debugging methods to diagnoze subtle runtime
inconsistency problem.
Enhancement
- store all the corruption or failure reasons in superblock
- detect meta inode, summary info, and block address inconsistency
- increase the limit for reserve_root for low-end devices
- add the number of compressed IO in iostat
Bug fix
- DIO write fix for zoned devices
- do out-of-place writes for cold files
- fix some stat updates (FS_CP_DATA_IO, dirty page count)
- fix race condition on setting FI_NO_EXTENT flag
- fix data races when freezing super
- fix wrong continue condition check in GC
- do not allow ATGC for LFS mode
In addition, there're some code enhancement and clean-ups as usual.

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

This is beneficial for real world applications that end up issuing lots of system calls as part of handling work. Normal task_work will always execute as we transition in and out of the kernel, even for "unrelated" system calls.

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"

"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.

mm/khugepaged: add tracepoint to hpage_collapse_scan_file()

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.

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.
