The first two changes that involve files outside of fs/ext4:
- submit_bh() can never return an error, so change it to return void,
and remove the unused checks from its callers
- fix I_DIRTY_TIME handling so it will be set even if the inode
already has I_DIRTY_INODE
Performance:
- Always enable i_version counter (as btrfs and xfs already do).
Remove some uneeded i_version bumps to avoid unnecessary nfs cache
invalidations.
- Wake up journal waters in FIFO order, to avoid some journal users
from not getting a journal handle for an unfairly long time.
- In ext4_write_begin() allocate any necessary buffer heads before
starting the journal handle.
- Don't try to prefetch the block allocation bitmaps for a read-only
file system.
Bug Fixes:
- Fix a number of fast commit bugs, including resources leaks and out
of bound references in various error handling paths and/or if the fast
commit log is corrupted.
- Avoid stopping the online resize early when expanding a file system
which is less than 16TiB to a size greater than 16TiB.
- Fix apparent metadata corruption caused by a race with a metadata
buffer head getting migrated while it was trying to be read.
- Mark the lazy initialization thread freezable to prevent suspend
failures.
- Other miscellaneous bug fixes.
Cleanups:
- Break up the incredibly long ext4_full_super() function by
refactoring to move code into more understandable, smaller
functions.
- Remove the deprecated (and ignored) noacl and nouser_attr mount
option.
- Factor out some common code in fast commit handling.
- Other miscellaneous cleanups.

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"

linux-kselftest-kunit-6.1-rc1
This KUnit update for Linux 6.1-rc1 consists of several documentation
fixes, UML related cleanups, and a feature to enable/disable KUnit
tests. This update includes the following change to
- rename all_test_uml.config, use it for --alltests
Note: if anyone was using all_tests_uml.config, this change breaks them.
This change simplifies the usage and eliminates the need to type:
--kunitconfig=tools/testing/kunit/configs/all_tests_uml.config.
A simple workaround to create a symlink to the new name can solve the
problem for anyone using all_tests_uml.config.
all_tests_uml.config should work across ~all architectures.

Pull KUnit updates from Shuah Khan:
"Several documentation fixes, UML related cleanups, and a feature to
enable/disable KUnit tests
This includes the change to rename all_test_uml.config, and use it for
'--alltests'. Note: if anyone was using all_tests_uml.config, this
change breaks them.
This change simplifies the usage and eliminates the need to type:
--kunitconfig=tools/testing/kunit/configs/all_tests_uml.config
A simple workaround to create a symlink to the new name can solve the
problem for anyone using all_tests_uml.config.
all_tests_uml.config should work across ~all architectures"

perf mem/c2c: Avoid printing empty lines for unsupported events
The 'perf mem' and 'perf c2c' tools can be used with 3 different events: load, store and combined load-store. Some architectures might support only partial set of events in which case, perf prints an empty line for unsupported events. Avoid that. Ex, AMD Zen cpus supports only combined load-store event and does not support individual load and store event.

perf mem/c2c: Add load store event mappings for AMD
The 'perf mem' and 'perf c2c' tools are wrappers around 'perf record' with mem load/ store events. IBS tagged load/store sample provides most of the information needed for these tools. Wire in the "ibs_op//" event as mem-ldst event for AMD. There are some limitations though: Only load/store micro-ops provide mem/c2c information. Whereas, IBS does not have a way to choose a particular type of micro-op to tag. This results in many non-LS micro-ops being tagged which appear as N/A in the perf report. IBS, being an uncore pmu from kernel point of view[1], does not support per process monitoring. Thus, perf mem/c2c on AMD are currently supported in per-cpu mode only. Example: $ sudo perf mem record -- -c 10000 ^C[ perf record: Woken up 227 times to write data ] [ perf record: Captured and wrote 58.760 MB perf.data (836978 samples) ] $ sudo perf mem report -F mem,sample,snoop Samples: 836K of event 'ibs_op//', Event count (approx.): 8418762 Memory access Samples Snoop N/A 700620 N/A L1 hit 126675 N/A L2 hit 424 N/A L3 hit 664 HitM L3 hit 10 N/A Local RAM hit 2 N/A Remote RAM (1 hop) hit 8558 N/A Remote Cache (1 hop) hit 3 N/A Remote Cache (1 hop) hit 2 HitM Remote Cache (2 hops) hit 10 HitM Remote Cache (2 hops) hit 6 N/A Uncached hit 4 N/A $ [1]: https://lore.kernel.org/lkml/20220829113347.295-1-ravi.bangoria@amd.com Signed-off-by: Ravi Bangoria <ravi.bangoria@amd.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Ali Saidi <alisaidi@amazon.com> Cc: Ananth Narayan <ananth.narayan@amd.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Borislav Petkov <bp@alien8.de> Cc: Dave Hansen <dave.hansen@linux.intel.com> Cc: H.

arm64 updates for 6.1:
- arm64 perf: DDR PMU driver for Alibaba's T-Head Yitian 710 SoC, SVE vector granule register added to the user regs together with SVE perf extensions documentation. - SVE updates: add HWCAP for SVE EBF16, update the SVE ABI documentation to match the actual kernel behaviour (zeroing the registers on syscall rather than "zeroed or preserved" previously). - More conversions to automatic system registers generation. - vDSO: use self-synchronising virtual counter access in gettimeofday() if the architecture supports it. - arm64 stacktrace cleanups and improvements. - arm64 atomics improvements: always inline assembly, remove LL/SC trampolines. - Improve the reporting of EL1 exceptions: rework BTI and FPAC exception handling, better EL1 undefs reporting. - Cortex-A510 erratum 2658417: remove BF16 support due to incorrect result. -

ARM: SoC code changes for 6.1
The main changes this time are for the organization of the Kconfig files, introducing per-vendor top-level options on arm64 to match those on arm32, and making the platform selection on arm32 more uniform, in particular for the remaining StrongARM platforms that still have a couple of special cases compared to the more recent ones. I also did a cleanup of the old Footbridge platform, which was the last holdout for the phys_to_dma()/dma_to_phys() interface that is now completely gone from arm32, completing work started by Christoph Hellwig. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmM+n3EACgkQmmx57+YA GNlnjA/+JR/0Y8gzRw6lGLB254R1zLqKzoZC065+zk++qN/t9pIEAvICaTO7ooIY Iz79crIyQ7aJptVfDyb44hrC23sBsY/ujkh7WmfLDAs7Jf9a1xOgcQONz6uOk+3p qsCXEjyn6O4EPtCBxiICA7vcVUAeM+wkcuV2KQnW9b4CNlLXdhyn1ijwnGO4Zm6g h2w0gX2TVkoR2ZSqWh5CCk9OOfgQRrHGMHzX0iRXtYApJk/zA8ywnuRsqts8R3lu 04Jl17szmMoeN2RQjf/gTJc7xpWvs7SzfyNTXXoXmB7x9c27eQXyoUpWC9o/BPPb YNqv2Xmm0+cMsmPvkY/7poDlPMObh9exV2dDQ3XKoyoVPu+hBL4AsXMchQ7rsrVk +FvdTxZTpl42sx9KitRQG/7WZ1pmxBBcFVB4fmVJcCF4OcOpXH7i1VmsB6PAOaIF CKUpaIjnTZ1VbqhADqCzRfUSI4HiAHuo886rAYcCK3K47UpLjBwcwOTyXZccG0SL z9IQkm53DgsJVLEUmtwAfVF57SciWxmQZid7vM2xQX/03pwO2/x4d347EcJJZcHS vuqWZD0Wp3VBuj2fLFk83WaaQJzP5rzJAewKbR4KyxraMyTvOEYVBa18AMnZQ6sw aFecU9YXa8PhgaiFrfepZcTby0Bm+YSc8ko80se44zz07kZW/y8= =xsKV -----END PGP SIGNATURE----- Merge tag 'arm-soc-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC updates from Arnd Bergmann: "The main changes this time are for the organization of the Kconfig files, introducing per-vendor top-level options on arm64 to match those on arm32, and making the platform selection on arm32 more uniform, in particular for the remaining StrongARM platforms that still have a couple of special cases compared to the more recent ones.

ARM: devicetree updates for 6.1
Most of the changes fall into one of three categories: adding support
for additional devices on existing machines, cleaning up issues found
by the ongoing conversion to machine-readable bindings, and addressing
minor mistakes in the existing DT data.
Across SoC vendors, Qualcomm and Freescale stick out as getting the most
updates, which corresponds to their dominance in the mobile phone and
embedded industrial markets, respectively.
There are 636 non-merge changeset in this branch, which is a little
lower than most times, but more importantly we only add 36 machine
files, which is about half of what we had the past few releases.
Eight new SoCs are added, but all of them are variations of already
supported SoC families, and most of them come with one reference board
design from the SoC vendor:
- Mediatek MT8186 is a Chromebook/Tablet type SoC, similar to the
MT65xx series of phone SoCs, with two Cortex-A76 and six Cortex-A55
cores.
- TI AM62A is another member of the K3 family with Cortex-A53 cores,
this one is targetted at Video/Vision processing for industrial
and automotive applications.
- NXP i.MX8DXL is another chip for this market in the ever-growing
i.MX8 family, this one again with two Cortex-A35 cores.
- Renesas R-Car H3Ne-1.7G (R8A779MB) and R-Car V3H2 (R8A77980A) are
minor updates of R8A77951 and R8A77980, respectively.
- Qualcomm IPQ8064-v2.0, IPQ8062 and IPQ8065 are all variants of the
IPQ8064 chip, with minimally different features.
The AMD Pensando Elba and Apple M1 Ultra SoC support was getting close
this time, but in the end did not make the cut.
The new machines based on existing SoC support are fairly uneventful:
- Sony Xperia 1 IV is a fairly recent phone based on Qualcomm
Snapdragon 8 Gen 1.
- Three Samsung phones based on Snapdragon 410: Galaxy E5, E7 and
Grand Max. These are added for both 32-bit and 64-bit kernels,
as they originally shipped running 32-bit code.
- Two new servers using AST2600 BMCs: AMD DaytonaX and Ampere
Mt. Mitchell
- Three new machines based on Rockchips RK3399 and RK3566:
Anberic RG353P and RG503, Pine64 Pinephone Pro, Open AI Lab
- Multiple NXP i.MX6/i.MX8 based boards: Kontron SL/BL i.MX8MM OSM-S,
i.MX8MM Gateworks GW7904, MSC SM2S-IMX8PLUS SoM and carrier board
- Two development boards in the Microchip AT91 family:
SAMA5D3-EDS and lan966x-pcb8290.
- Minor variants of existing boards using Amlogic, Broadcom, Marvell,
Rockchips, Freescale Layerscape and Socionext Uniphier SoCs.

ARM: driver updates for 6.1
The drivers branch for 6.1 is a bit larger than for most releases. Most
of the changes come from SoC maintainers for the drivers/soc subsystem:
- A new driver for error handling on the NVIDIA Tegra
'control backbone' bus.
- A new driver for Qualcomm LLCC/DDR bandwidth measurement
- New Rockchip rv1126 and rk3588 power domain drivers
- DT binding updates for memory controllers, older Rockchip
SoCs, various Mediatek devices, Qualcomm SCM firmware
- Minor updates to Hisilicon LPC bus, the Allwinner SRAM
driver, the Apple rtkit firmware driver, Tegra firmware
- Minor updates for SoC drivers (Samsung, Mediatek, Renesas,
Tegra, Qualcomm, Broadcom, NXP, ...)
There are also some separate subsystem with downstream maintainers that
merge updates this way:
- Various updates and new drivers in the memory controller
subsystem for Mediatek and Broadcom SoCs
- Small set of changes in preparation to add support for FF-A
v1.1 specification later, in the Arm FF-A firmware subsystem
- debugfs support in the PSCI firmware subsystem

perf stat: Fix cpu check to use id.cpu.cpu in aggr_printout()
'perf stat' has options to aggregate the counts in different modes like
per socket, per core etc. The function "aggr_printout" in
util/stat-display.c which is used to print the aggregates, has a check
for cpu in case of AGGR_NONE.
This check was originally using condition : "if (id.cpu.cpu > -1)". But
this got changed after commit

perf test: Add build infra for perf test tools for ARM CoreSight tests
This adds the initial build infrastructure (makefiles maintainers
information) for adding follow-on tests for CoreSight.
Committer notes:
Remove the installation of tests/shell/coresight/*.sh, as there are no
files there yet and thus, at this point, make install fails.
Use $(QUIET_CLEAN) to avoid having extraneous output in the 'make clean'
output.
Also use @$(MAKE) in tools/perf/tests/shell/coresight/Makefile as $(Q)
is not turning into @ when V=1 isn't used, i.e. in the default case it
is not being quiet.
The >/dev/null in the all for tools/perf/tests/shell/coresight/Makefile
is to avoid this:
make[4]: Nothing to be done for 'all'.
make[4]: Nothing to be done for 'all'.
make[4]: Nothing to be done for 'all'.
DESCEND plugins
GEN /tmp/build/perf/python/perf.so
make[4]: Nothing to be done for 'all'.
INSTALL trace_plugins
On !arm64 where nothing is done on the main target for
tools/perf/tests/shell/coresight/*/Makefile.

ftrace: Create separate entry in MAINTAINERS for function hooks
The function hooks (ftrace) is a completely different subsystem from the general tracing. It manages how to attach callbacks to most functions in the kernel. It is also used by live kernel patching. It really is not part of tracing, although tracing uses it. Create a separate entry for FUNCTION HOOKS (FTRACE) to be separate from tracing itself in the MAINTAINERS file. Perhaps it should be moved out of the kernel/trace directory, but that's for another time.

perf test: Introduce script for data symbol testing
The test is designed with a data structure with 64-byte alignment, it has two fields "data1" and "data2", and other fields are reserved. Using the "perf mem" command, we can record and report memory samples for a self-contained workload with 1 second duration. If no samples are obtained for the data structure "buf1", it reports failure; and by checking the offset in structure "buf1", if the memory samples aren't for the "data1" and "data2" fields, it means wrong data symbol parsing and returns failure.

powerpc: Don't add __powerpc_ prefix to syscall entry points
When using syscall wrappers the __SYSCALL_DEFINEx() and related macros
add a "__powerpc_" prefix to all syscall entry points.
So for example sys_mmap becomes __powerpc_sys_mmap.
This risks breaking workflows and tools that expect the old naming
scheme. At a minimum setting a breakpoint on eg. sys_mmap with gdb no
longer works.
There seems to be no compelling reason to add the "__powerpc_" prefix,
other than that it follows what some other arches do (x86, arm64, s390).
But unlike other arches powerpc doesn't always enable syscall wrappers,
so the syscall entry points can change name depending on CONFIG options.
For those reasons drop the "__powerpc_" prefix, reverting to the
existing naming.
Doing so reveals two prototypes in signal.h that have the incorrect type
when syscall wrappers are enabled. There are already prototypes for both
functions in syscalls.h, so drop the ones from signal.h.
