We're hitting some issues with uninitialized struct padding, flagged by kmsan. They appear to be falso positives, otherwise bch2_accounting_validate() would have flagged them as "junk at end". But for now, we'll need to initialize disk_accounting_pos with memset(). This adds a new helper, bch2_disk_accounting_mod2(), that initializes a disk_accounting_pos and does the accounting mod all at once - so overall things actually get slightly more ergonomic. BCH_DISK_ACCOUNTING_replicas keys are left for now; KMSAN isn't warning about them and they're a bit special. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

read_word_at_a_time() is allowed to read out of bounds by straddling the end of an allocation (and the caller is expected to then mask off out-of-bounds data). This works as long as the caller guarantees that the access won't hit a pagefault (either by ensuring that addr is aligned or by explicitly checking where the next page boundary is). Such out-of-bounds data could include things like KASAN redzones, adjacent allocations that are concurrently written to, or simply an adjacent struct field that is concurrently updated. KCSAN should ignore racy reads of OOB data that is not actually used, just like KASAN, so (similar to the code above) change read_word_at_a_time() to use __no_sanitize_or_inline instead of __no_kasan_or_inline, and explicitly inform KCSAN that we're reading the first byte. We do have an instrument_read() helper that calls into both KASAN and KCSAN, but I'm instead open-coding that here to avoid having to pull the entire instrumented.h header into rwonce.h. Also, since this read can be racy by design, we should technically do READ_ONCE(), so add that.

When arm64 is built with LTO, it upgrades READ_ONCE() to ldar / ldapr (load-acquire) to avoid issues that can be caused by the compiler optimizing away implicit address dependencies. Unlike plain loads, these load-acquire instructions actually require an aligned address. For now, fix it by removing the READ_ONCE() that the buggy commit introduced.

Pull SoC devicetree updates from Arnd Bergmann:
"There is new support for additional on-chip devices on Apple,
Mediatek, Renesas, Rockchip, Samsung, Google, TI, ST, Nvidia and
Amlogic devices.
The Arm Morello reference platform gets a devicetree for booting in
normal aarch64 mode. The hardware supports experimental CHERI support,
which requires a modified kernel.
The AMD (formerly Xilinx) Versal NET SoC gets added, this is a
combined FPGA with Cortex-A78 CPUs in a SoC.
Six new ST STM32MP2 SoC variants are added. Like the earlier
STM32MP25, the MP211, MP213, MP215, MP231, MP233 and MP235 models are
based on one or two Cortex-A35 cores but each feature a different set
of I/O devices.
Mediatek MT8370 is a minor variation of MT8390 with fewer CPU and GPU
cores
Apple T2 is the baseboard management controller on earlier Intel CPU
based Macs, with 16 models now gaining initial support.
All the above come with dts files for the reference boards. In
addition, these boards are added for the SoCs that are already
supported:
- The Milk-V Jupiter board based on SpacemiT K1/M1
- NetCube Systems Kumquat board based on the 32-bit Allwinner V3s SoC
- Three boards based on 32-bit stm32mp1
- 11 distinct board variants from Toradex and one from Variscite, all
based on i.MX6
- Google Pixel Pro 6 phone based on gs101 (Tensor)
- Three additional variants of the i.MX8MP based "Skov" board
- A second variant of the i.MX95 EVK board
- Two boards based on Renesas SoCs
- Four boards based the Rockchip RK35xx series, plus the RK3588 'MNT
Reform 2' laptop"

Pull btrfs updates from David Sterba:
"User visible changes:
- fall back to buffered write if direct io is done on a file that
requires checksums
- this avoids a problem with checksum mismatch errors, observed
e.g. on virtual images when writes to pages under writeback
cause the checksum mismatch reports
- this may lead to some performance degradation but currently the
recommended setup for VM images is to use the NOCOW file
attribute that also disables checksums
- fast/realtime zstd levels -15 to -1
- supported by mount options (compress=zstd:-5) and defrag ioctl
- improved speed, reduced compression ratio, check the commit for
sample measurements
- defrag ioctl extended to accept negative compression levels
- subpage mode
- remove warning when subpage mode is used, the feature is now
reasonably complete and tested
- in debug mode allow to create 2K b-tree nodes to allow testing
subpage on x86_64 with 4K pages too
Performance improvements:
- in send, better file path caching improves runtime (on sample load
by -30%)
- on s390x with hardware zlib support prepare the input buffer in a
better way to get the best results from the acceleration
- minor speed improvement in encoded read, avoid memory allocation in
synchronous mode
Core:
- enable stable writes on inodes, replacing manually waiting for
writeback and allowing to skip that on inodes without checksums
- add last checks and warnings for out-of-band dirty writes to pages,
requiring a fixup ("fixup worker"), this should not be necessary
since 5.8 where get_user_page() and pin_user_pages*() prevent this
- long history behind that, we'll be happy to remove the whole
infrastructure in the near future
- more folio API conversions and preparations for large folio support
- subpage cleanups and refactoring, split handling of data and
metadata to allow future support for large folios
- readpage works as block-by-block, no change for normal mode, this
is preparation for future subpage updates
- block group refcount fixes and hardening
- delayed iput fixes
- in zoned mode, fix zone activation on filesystem with missing
devices
Cleanups:
- inode parameter cleanups
- path auto-freeing updates
- code flow simplifications in send
- redundant parameter cleanups"

Pull bcachefs updates from Kent Overstreet:
"On disk format is now soft frozen: no more required/automatic are
anticipated before taking off the experimental label.
Major changes/features since 6.14:
- Scrub
- Blocksize greater than page size support
- A number of "rebalance spinning and doing no work" issues have been
fixed; we now check if the write allocation will succeed in
bch2_data_update_init(), before kicking off the read.
There's still more work to do in this area. Later we may want to
add another bitset btree, like rebalance_work, to track "extents
that rebalance was requested to move but couldn't", e.g. due to
destination target having insufficient online devices.
- We can now support scaling well into the petabyte range: latest
bcachefs-tools will pick an appropriate bucket size at format time
to ensure fsck can run in available memory (e.g. a server with
256GB of ram and 100PB of storage would want 16MB buckets).
On disk format changes:
- 1.21: cached backpointers (scalability improvement)
Cached replicas now get backpointers, which means we no longer rely
on incrementing bucket generation numbers to invalidate cached
data: this lets us get rid of the bucket generation number garbage
collection, which had to periodically rescan all extents to
recompute bucket oldest_gen.
Bucket generation numbers are now only used as a consistency check,
but they're quite useful for that.
- 1.22: stripe backpointers
Stripes now have backpointers: erasure coded stripes have their own
checksums, separate from the checksums for the extents they contain
(and stripe checksums also cover the parity blocks). This is
required for implementing scrub for stripes.
- 1.23: stripe lru (scalability improvement)
Persistent lru for stripes, ordered by "number of empty blocks".
This is used by the stripe creation path, which depending on free
space may create a new stripe out of a partially empty existing
stripe instead of starting a brand new stripe.
This replaces an in-memory heap, and means we no longer have to
read in the stripes btree at startup.
- 1.24: casefolding
Case insensitive directory support, courtesy of Valve.
This is an incompatible feature, to enable mount with
-o version_upgrade=incompatible
- 1.25: extent_flags
Another incompatible feature requiring explicit opt-in to enable.
This adds a flags entry to extents, and a flag bit that marks
extents as poisoned.
A poisoned extent is an extent that was unreadable due to checksum
errors. We can't move such extents without giving them a new
checksum, and we may have to move them (for e.g. copygc or device
evacuate). We also don't want to delete them: in the future we'll
have an API that lets userspace ignore checksum errors and attempt
to deal with simple bitrot itself. Marking them as poisoned lets us
continue to return the correct error to userspace on normal read
calls.
Other changes/features:
- BCH_IOCTL_QUERY_COUNTERS: this is used by the new 'bcachefs fs top'
command, which shows a live view of all internal filesystem
counters.
- Improved journal pipelining: we can now have 16 journal writes in
flight concurrently, up from 4. We're logging significantly more to
the journal than we used to with all the recent disk accounting
changes and additions, so some users should see a performance
increase on some workloads.
- BCH_MEMBER_STATE_failed: previously, we would do no IO at all to
devices marked as failed. Now we will attempt to read from them,
but only if we have no better options.
- New option, write_error_timeout: devices will be kicked out of the
filesystem if all writes have been failing for x number of seconds.
We now also kick devices out when notified by blk_holder_ops that
they've gone offline.
- Device option handling improvements: the discard option should now
be working as expected (additionally, in -tools, all device options
that can be set at format time can now be set at device add time,
i.e. data_allowed, state).
- We now try harder to read data after a checksum error: we'll do
additional retries if necessary to a device after after it gave us
data with a checksum error.
- More self healing work: the full inode <-> dirent consistency
checks that are currently run by fsck are now also run every time
we do a lookup, meaning we'll be able to correct errors at runtime.
Runtime self healing will be flipped on after the new changes have
seen more testing, currently they're just checking for consistency.
- KMSAN fixes: our KMSAN builds should be nearly clean now, which
will put a massive dent in the syzbot dashboard"
