The integrity checker feature needs to be enabled at compile time
(BTRFS_FS_CHECK_INTEGRITY) and then enabled by mount options check_int*.
Although it provides some unique features which can not be provided by
any other sanity checks like tree-checker, it does not only have high
CPU and memory overhead, but is also a maintenance burden.
For example, it's the only caller of btrfs_map_block() with
@need_raid_map = 0.
Considering most btrfs developers are not even testing this feature, I'm
here to propose deprecation of this feature.
For now only warning messages will be printed, the feature itself would
still work.
Removal time has been set to 6.7 release.

The code for btrfs_add_excluded_extent() is trivial, it's just a
set_extent_bit() call. However it's defined in extent-tree.c but it is
only used (twice) in block-group.c. So open code it in block-group.c,
reducing the need to export a trivial function.
Also since the only caller btrfs_add_excluded_extent() is prepared to
deal with errors, stop ignoring errors from the set_extent_bit() call.

Currently find_first_extent_bit() returns a 0 if it found a range in the
given io tree and 1 if it didn't find any. There's no need to return any
errors, so make the return value a boolean and invert the logic to make
more sense: return true if it found a range and false if it didn't find
any range.

Currently btrfs_destroy_pinned_extent() is always returning 0 no matter
what and its caller ignores its return value (as well everything up in
the call chain). This is because this is called in the transaction abort
path, where we can't even deal with any errors since we are in a critical
situation already and cleanup of resources is done in a best effort
fashion.
So make btrfs_destroy_pinned_extent() return void.

The documentation for add_new_free_space() is stale and no longer correct:
1) It's no longer used only when caching a block group. It's also called
when creating a block group (btrfs_make_block_group()), when reading
a block group at mount time (read_one_block_group()) and when reading
the free space tree for a block group (typically the first time we
attempt to allocate from the block group);
2) It has nothing to do with pinned extents. It only deals with the
excluded extents io tree, which is used to track the locations of
super blocks in order to make sure we never add the location of a
super block to the free space cache of a block group.
So update the documention and also add a description of the arguments
and return values.

After commit 6bfd0133be ("btrfs: raid56: switch scrub path to use a
single function"), the raid56 implementation no longer uses different
endio functions for RMW/recover/scrub.
All read operations end in submit_read_wait_bio_list(), while all write
operations end in submit_write_bios(). This means quite some trace
events are out-of-date and no longer utilized.
This patch would unify the trace events into just two:
- trace_raid56_read()
Replaces trace_raid56_read_partial(), trace_raid56_scrub_read() and
trace_raid56_scrub_read_recover().
- trace_raid56_write()
Replaces trace_raid56_write_stripe() and
trace_raid56_scrub_write_stripe().

ACL support depends on the compile-time configuration option
CONFIG_BTRFS_FS_POSIX_ACL. Prior to mounting a btrfs filesystem, it is not
possible to determine whether ACL support has been compiled in. To address
this, add a sysfs interface, /sys/fs/btrfs/features/acl, and check for ACL
support in the system's btrfs.
To determine ACL support:
Return 0 indicates ACL is not supported:
$ cat /sys/fs/btrfs/features/acl
0
Return 1 indicates ACL is supported:
$ cat /sys/fs/btrfs/features/acl
1
IMO, this is a better approach, so that we also know if kernel is older.
On an older kernel
$ ls /sys/fs/btrfs/features/acl
ls: cannot access '/sys/fs/btrfs/features/acl': No such file or directory
mount a btrfs filesystem
$ cat /proc/self/mounts | grep btrfs | grep -q noacl
$ echo $?

Commit aca43fe839 ("btrfs: remove unused raid56 functions which were
dedicated for scrub") removed the special handling of RAID56 scrub for
missing device.
As scrub goes full mirror_num based recovery, that means if it hits a
missing device in RAID56, it would just try the next mirror, which would
go through the BTRFS_RBIO_READ_REBUILD operation.
This means there is no longer any use of BTRFS_RBIO_REBUILD_MISSING
operation and we can safely remove it.

The function btrfs_map_block() is a critical part of the btrfs storage
layer, which handles mapping of logical ranges to physical ranges.
Thus it's better to have some basic explanation, especially on the
following points:
- Segment split by various boundaries
As a continuous logical range may be split into different segments,
due to various factors like zones and RAID0/5/6/10 boundaries.
- The meaning of @mirror_num
- The possible single stripe optimization
- One deprecated parameter @need_raid_map
Just explicitly mark it deprecated so we're aware of the problem.

drivers/rnbd: restore sysfs interface to rnbd-client
Chuck reported [1] an IO hang problem on NFS exports that reside on SATA
devices and bisected to commit 615939a2ae ("blk-mq: defer to the normal
submission path for post-flush requests").
We analysed the IO hang problem, found there are two postflush requests
waiting for each other.
The first postflush request completed the REQ_FSEQ_DATA sequence, so go to
the REQ_FSEQ_POSTFLUSH sequence and added in the flush pending list, but
failed to blk_kick_flush() because of the second postflush request which
is inflight waiting in scheduler queue.
The second postflush waiting in scheduler queue can't be dispatched because
the first postflush hasn't released scheduler resource even though it has
completed by itself.
Fix it by releasing scheduler resource when the first postflush request
completed, so the second postflush can be dispatched and completed, then
make blk_kick_flush() succeed.
While at it, remove the check for e->ops.finish_request, as all
schedulers set that. Reaffirm this requirement by adding a WARN_ON_ONCE()
at scheduler registration time, just like we do for insert_requests and
dispatch_request.

Pull x86 fixes from Borislav Petkov:
"Extraordinary embargoed times call for extraordinary measures. That's
why this week's x86/urgent branch is larger than usual, containing all
the known fallout fixes after the SRSO mitigation got merged.
I know, it is a bit late in the game but everyone who has reported a
bug stemming from the SRSO pile, has tested that branch and has
confirmed that it fixes their bug.
Also, I've run it on every possible hardware I have and it is looking
good. It is running on this very machine while I'm typing, for 2 days
now without an issue. Famous last words...
- Use LEA ...%rsp instead of ADD %rsp in the Zen1/2 SRSO return
sequence as latter clobbers flags which interferes with fastop
emulation in KVM, leading to guests freezing during boot
- A fix for the DIV(0) quotient data leak on Zen1 to clear the
divider buffers at the right time
- Disable the SRSO mitigation on unaffected configurations as it got
enabled there unnecessarily
- Change .text section name to fix CONFIG_LTO_CLANG builds
- Improve the optprobe indirect jmp check so that certain
configurations can still be able to use optprobes at all
- A serious and good scrubbing of the untraining routines by PeterZ:
- Add proper speculation stopping traps so that objtool is happy
- Adjust objtool to handle the new thunks
- Make the thunk pointer assignable to the different untraining
sequences at runtime, thus avoiding the alternative at the
return thunk. It simplifies the code a bit too.
- Add a entry_untrain_ret() main entry point which selects the
respective untraining sequence
- Rename things so that they're more clear
- Fix stack validation with FRAME_POINTER=y builds
- Fix static call patching to handle when a JMP to the return thunk
is the last insn on the very last module memory page
- Add more documentation about what each untraining routine does and
why"

- Fix hardened usercopy BUG when using /proc based firmware update

Thanks to Nathan Lynch and Kees Cook.

powerpc/rtas_flash: allow user copy to flash block cache objects
blk_crypto_profile_init() calls lockdep_register_key(), which warns and
does not register if the provided memory is a static object.
blk-crypto-fallback currently has a static blk_crypto_profile and calls
blk_crypto_profile_init() thereupon, resulting in the warning and
failure to register.
Fortunately it is simple enough to use a dynamically allocated profile
and make lockdep function correctly.

As usual, mostly DT fixes for the major Arm platforms from Qualcomm and
NXP, plus a bit for Rockchips and others:
The qualcomm fixes mainly deal with their higher-end arm64 devices trees,
fixing issues in L3 interconnect, crypto, thermal, UFS and a regression
for the DSI phy.
NXP i.MX has two correctness fixes for the 64-bit chips, dealing with
the imx93 "anatop" module and the CSI interface. On the 32-bit side,
there are functional fixes for RTC, display and SD card intefaces.
Rockchip fixes are for wifi support on certain boards, a eMMC stability
and DT build warnings.
On TI OMAP, a regulator is described in DT to avoid problems with the
ethernet phy initialization.
The code changes include a missing MMIO serialization on OMAP, plus a
few minor fixes on ASpeed and AMD/Zynq chips.

"Just one partial revert for a commit from the merge window that caused

asm-generic: partially revert "Unify uapi bitsperlong.h for arm64, riscv and loongarch"
In production we were seeing a variety of WARN_ON()'s in the extent_map
code, specifically in btrfs_drop_extent_map_range() when we have to call
add_extent_mapping() for our second split.
Consider the following extent map layout
PINNED
[0 16K) [32K, 48K)
and then we call btrfs_drop_extent_map_range for [0, 36K), with
skip_pinned == true. The initial loop will have
start = 0
end = 36K
len = 36K
we will find the [0, 16k) extent, but since we are pinned we will skip
it, which has this code
start = em_end;
if (end != (u64)-1)
len = start + len - em_end;
em_end here is 16K, so now the values are
start = 16K
len = 16K + 36K - 16K = 36K
len should instead be 20K. This is a problem when we find the next
extent at [32K, 48K), we need to split this extent to leave [36K, 48k),
however the code for the split looks like this
split->start = start + len;
split->len = em_end - (start + len);
In this case we have
em_end = 48K
split->start = 16K + 36K // this should be 16K + 20K
split->len = 48K - (16K + 36K) // this overflows as 16K + 36K is 52K
and now we have an invalid extent_map in the tree that potentially
overlaps other entries in the extent map. Even in the non-overlapping
case we will have split->start set improperly, which will cause problems
with any block related calculations.
We don't actually need len in this loop, we can simply use end as our
end point, and only adjust start up when we find a pinned extent we need
to skip.
Adjust the logic to do this, which keeps us from inserting an invalid
extent map.
We only skip_pinned in the relocation case, so this is relatively rare,
except in the case where you are running relocation a lot, which can
happen with auto relocation on.

While performing certain power-off sequences, PCI drivers are
called to suspend and resume their underlying devices through
PCI PM (power management) interface. However this NIC hardware
does not support PCI PM suspend/resume operations so system wide
suspend/resume leads to bad MFW (management firmware) state which
causes various follow-up errors in driver when communicating with
the device/firmware afterwards.
To fix this driver implements PCI PM suspend handler to indicate
unsupported operation to the PCI subsystem explicitly, thus avoiding
system to go into suspended/standby mode.
Without this fix device/firmware does not recover unless system
is power cycled.
