Please note that to have the -b option (BPF) working above one has to build
with BUILD_BPF_SKEL=1.
- Add more 'perf test' entries to test these new features.
- Add Ian Rogers to MAINTAINERS as a perf tools reviewer.
- Add support for retire latency feature (pipeline stall of a instruction
compared to the previous one, in cycles) present on some Intel processors.
- Add 'perf c2c' report option to show false sharing with adjacent cachelines, to
be used in machines with cacheline prefetching, where accesses to a cacheline
brings the next one too.
- Skip 'perf test bpf' when the required kernel-debuginfo package isn't installed.
perf script:
- Add 'cgroup' field for 'perf script' output:
$ perf record --all-cgroups -- true
$ perf script -F comm,pid,cgroup
true 337112 /user.slice/user-657345.slice/user@657345.service/...

- Add support for showing branch speculation information in 'perf
script' and in the 'perf report' raw dump (-D).
perf record:
- Fix 'perf record' segfault with --overwrite and --max-size.
Intel PT:
- Add support for synthesizing "cycle" events from Intel PT traces as we
support "instruction" events when Intel PT CYC packets are available. This
enables much more accurate profiles than when using the regular 'perf record -e
cycles' (the default) when the workload lasts for very short periods (<10ms).
- .plt symbol handling improvements, better handling IBT (in the past
MPX) done in the context of decoding Intel PT processor traces, IFUNC
symbols on x86_64, static executables, understanding .plt.got symbols on
x86_64.
- Add a 'perf test' to test symbol resolution, part of the .plt
improvements series, this tests things like symbol size in contexts
where only the symbol start is available (kallsyms), etc.
- Better handle auxtrace/Intel PT data when using pipe mode (perf record sleep 1|perf report).
- Fix symbol lookup with kcore with multiple segments match stext,
getting the symbol resolution to just show DSOs as unknown.
ARM:
- Timestamp improvements for ARM64 systems with ETMv4 (Embedded Trace
Macrocell v4).
- Ensure ARM64 CoreSight timestamps don't go backwards.
- Document that ARM64 SPE (Statistical Profiling Extension) is used with 'perf c2c/mem'.
- Add raw decoding for ARM64 SPEv1.2 previous branch address.
- Update neoverse-n2-v2 ARM vendor events (JSON tables): topdown L1, TLB,
cache, branch, PE utilization and instruction mix metrics.
- Update decoder code for OpenCSD version 1.4, on ARM64 systems.
- Fix command line auto-complete of CPU events on aarch64.
perf test/bench:
- Switch basic BPF filtering test to use syscall tracepoint to avoid the
variable number of probes inserted when using the previous probe point
(do_epoll_wait) that happens on different CPU architectures.
- Fix DWARF unwind test by adding non-inline to expected function in a
backtrace.
- Use 'grep -c' where the longer form 'grep | wc -l' was being used.
- Add getpid and execve benchmarks to 'perf bench syscall'.
Miscellaneous:
- Avoid d3-flame-graph package dependency in 'perf script flamegraph',
making this feature more generally available.
- Add JSON metric events to present CPI stall cycles in Power10.
- Assorted improvements/refactorings on the JSON metrics parsing code.
Build:
- Fix 'perf probe' and 'perf test' when libtraceevent isn't linked, as
several tests use tracepoints, those should be skipped.
- More fallout fixes for the removal of tools/lib/traceevent/.
- Fix build error when linking with libpfm.

...
With the change that allows to read the "trace" file without disabling
writing to the ring buffer, there was an integrity check of the ring
buffer in the iterator read code, that expected the ring buffer to be
write disabled. This caused the integrity check to trigger when stress
reading the "trace" file while writing was happening.
The integrity check is a bit aggressive (and has never triggered in
practice). Change it so that it checks just the integrity of the linked
pages without clearing the flags inside the pointers. This removes the

Pull tracing fix from Steven Rostedt:
"Fix race that causes a warning of corrupt ring buffer
With the change that allows to read the "trace" file without disabling
writing to the ring buffer, there was an integrity check of the ring
buffer in the iterator read code, that expected the ring buffer to be
write disabled. This caused the integrity check to trigger when stress
reading the "trace" file while writing was happening.
The integrity check is a bit aggressive (and has never triggered in
practice). Change it so that it checks just the integrity of the
linked pages without clearing the flags inside the pointers. This
removes the warning that was being triggered"
[ Heh. This was supposed to have gone in last week before the 6.2
release, but Steven forgot to actually add me to the participants of
the pull request, so here it is, a week later - Linus ]

Merge tag '6.3-rc-smb3-client-fixes' of git://git.samba.org/sfrench/cifs-2.6
Pull cifs client updates from Steve French:
"The largest subset of this is from David Howells et al: making the
cifs/smb3 driver pass iov_iters down to the lowest layers, directly to
the network transport rather than passing lists of pages around,
helping multiple areas:
- Pin user pages, thereby fixing the race between concurrent DIO read
and fork, where the pages containing the DIO read buffer may end up
belonging to the child process and not the parent - with the result
that the parent might not see the retrieved data.
- cifs shouldn't take refs on pages extracted from non-user-backed
iterators (eg. KVEC). With these changes, cifs will apply the
appropriate cleanup.
- Making it easier to transition to using folios in cifs rather than
pages by dealing with them through BVEC and XARRAY iterators.
- Allowing cifs to use the new splice function
The remainder are:
- fixes for stable, including various fixes for uninitialized memory,
wrong length field causing mount issue to very old servers,
important directory lease fixes and reconnect fixes
- cleanups (unused code removal, change one element array usage, and
a change form strtobool to kstrtobool, and Kconfig cleanups)
- SMBDIRECT (RDMA) fixes including iov_iter integration and UAF fixes
- reconnect fixes
- multichannel fixes, including improving channel allocation (to
least used channel)
- remove the last use of lock_page_killable by moving to
folio_lock_killable"

Two significant security enhancements are part of this release:
* NFSD's RPC header encoding and decoding, including RPCSEC GSS
and gssproxy header parsing, has been overhauled to make it
more memory-safe.
* Support for Kerberos AES-SHA2-based encryption types has been
added for both the NFS client and server. This provides a clean
path for deprecating and removing insecure encryption types
based on DES and SHA-1. AES-SHA2 is also FIPS-140 compliant, so
that NFS with Kerberos may now be used on systems with fips
enabled.
In addition to these, NFSD is now able to handle crossing into an
auto-mounted mount point on an exported NFS mount. A number of
fixes have been made to NFSD's server-side copy implementation.
RPC metrics have been converted to per-CPU variables. This helps
reduce unnecessary cross-CPU and cross-node memory bus traffic,
and significantly reduces noise when KCSAN is enabled.

"There's a couple of bug fixes, some cleanups for inconsistent variable
names and reduction of struct boxing and unboxing in the logging code.
More work is pending, which will begin reworking allocation group
lifetimes and finally replace confusing indirect calls to the
allocator with actual ... function calls. But I want to let that
experience another week of testing.
Summary:
- Eliminate repeated boxing and unboxing of log item parameters
- Clean up some confusing variable names in the log item code
- Fix a deadlock when doing unwritten extent conversion that causes a
bmbt split when there are sustained memory shortages and the worker
pool runs out of worker threads

- Change when the iomap page_done function is called so that we still
have a locked folio in the success case. This fixes a writeback race
in gfs2.
- Change when the iomap page_prepare function is called so that gfs2
can recover from OOM scenarios more gracefully.
- Rename the iomap page_ops to folio_ops, since they operate on folios
now.

* Cleanup of libata FUA handling. This falls short of enabling FUA for
ATA drives that support it by default as there were concerns that
old drives would break. The series howeverfixes several issues with
the FUA support to ensure that FUA is reported as being supported
only for drives that can handle all possible write cases (NCQ and
non-NCQ). A check in the block layer is also added to ensure that we
never see read FUA commands (current behavior). From me.
* Several patches to move the old PARIDE (parallel port IDE) driver to
libata as pata_parport. Given that this driver also needs protocol
modules, the driver code resides in its own pata_parport directoy
under drivers/ata. From Ondrej.

This has been a fairly quiet release for SPI, though it is likely that
the next release will have some big changes as there's some preparatory
work for multiple chip select support gone in - the rest of the code is
on the list but will need to be rebased onto -rc1. Otherwise there's a couple
of new tunables for chip select timings, some new devices and smaller
device specific updates and fixes.
- Support for configuring the hold and minimum inactive times for chip
selects.
- Beginnings of support for supporting devices which have multiple chip
selects on a single device.
- Support for newer Broadcom HSSPI and Intel controllers, Silicon Labs
EM3581 and SI3210.
There is a simple add/add conflict in MAINTAINERS with the I2C tree.

The majority of works in this cycle are about ASoC spread over trees.
Most of them are for new devices and cleanups / refactoring works,
and not much significant changes are seen in the core side.
Below are some highlights:
ASoC:
- Continued refactoring to move into common helper functions
- Lots of DT schema conversons and stylistic nits
- Continued work on building out the new SOF IPC4 scheme
- Continued work for Intel AVS
- New drivers for Awinc AT88395, Infineon PEB2466, Iron Device
SMA1303, Mediatek MT8188, Realtek RT712, Renesas IDT821034,
Samsung/Tesla FSD SoC I2S, and TI TAS5720A-Q1
ALSA:
- A few cleanups to make the remove callbacks to void returns
- FireWire refactoring and enhancements
- PCM kselftest enhancements

Commit 74e19ef0ff80 ("uaccess: Add speculation barrier to
copy_from_user()") built fine on x86-64 and arm64, and that's the extent
of my local build testing.
It turns out those got the <linux/nospec.h> include incidentally through
other header files (<linux/kvm_host.h> in particular), but that was not
true of other architectures, resulting in build errors
kernel/bpf/core.c: In function ‘___bpf_prog_run’:
kernel/bpf/core.c:1913:3: error: implicit declaration of function ‘barrier_nospec’
so just make sure to explicitly include the proper <linux/nospec.h>
header file to make everybody see it.

Convert gfs2_page_add_databufs() to folios and rename it to
gfs2_trans_add_databufs().
Cc: Matthew Wilcox <willy@infradead.org>
Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
The ->writepage() and ->writepages() operations are supposed to write
entire pages. However, on filesystems with a block size smaller than
PAGE_SIZE, __gfs2_jdata_writepage() only adds the first block to the
current transaction instead of adding the entire page. Fix that.

Initial support of HID-BPF (Benjamin Tissoires)
The history is a little long for this series, as it was intended to be
sent for v6.2. However some last minute issues forced us to postpone it
to v6.3.
Conflicts:
* drivers/hid/i2c-hid/Kconfig:
commit bf7660dab30d ("HID: stop drivers from selecting CONFIG_HID")
conflicts with commit 2afac81dd165 ("HID: fix I2C_HID not selected
when I2C_HID_OF_ELAN is")
the resolution is simple enough: just drop the "default" and "select"
lines as the new commit from Arnd is doing
