e4655196e2 coccinelle: misc: minmax: Suppress reports for err returns
Most of the people prefer:

return ret < 0 ? ret: 0;

than:

return min(ret, 0);

Let's tweak the cocci file to ignore those lines completely.

cef27048e5 bcachefs fixes for 6.9-rc5
various recovery fixes:
 
 - fixes for the btree_insert_entry being resized on path allocation
   btree_path array recently became dynamically resizable, and
   btree_insert_entry along with it; this was being observed during
   journal replay, when write buffer btree updates don't use the write
   buffer and instead use the normal btree update path
 - multiple fixes for deadlock in recovery when we need to do lots of
   btree node merges; excessive merges were clocking up the whole
   pipeline
 - write buffer path now correctly does btree node merges when needed
 - fix failure to go RW when superblock indicates recovery passes needed
   (i.e. to complete an unfinished upgrade)
 
 various unsafety fixes - test case contributed by a user who had two
 drives out of a six drive array write out a whole bunch of garbage after
 power failure
 
 new (tiny) on disk format feature: since it appears the btree node scan
 tool will be a more regular thing (crappy hardware, user error) - this
 adds a 64 bit per-device bitmap of regions that have ever had btree
 nodes.
 
 a path->should_be_locked fix, from a larger patch series tightening up
 invariants and assertions around btree transaction and path locking
 state; this particular fix prevents us from keeping around btree_paths
 that are no longer needed.

ad29cf999a bcachefs: set_btree_iter_dontneed also clears should_be_locked
This is part of a larger series cleaning up the semantics of
should_be_locked and adding assertions around it; if we don't need an
iterator/path anymore, it clearly doesn't need to be locked.

27c15ed297 bcachefs: bch_member.btree_allocated_bitmap
This adds a small (64 bit) per-device bitmap that tracks ranges that
have btree nodes, for accelerating btree node scan if it is ever needed.

- New helpers, bch2_dev_btree_bitmap_marked() and
  bch2_dev_bitmap_mark(), for checking and updating the bitmap

- Interior btree update path updates the bitmaps when required

- The check_allocations pass has a new fsck_err check,
  btree_bitmap_not_marked

- New on disk format version, mi_btree_mitmap, which indicates the new
  bitmap is present

- Upgrade table lists the required recovery pass and expected fsck error

- Btree node scan uses the bitmap to skip ranges if we're on the new
  version

Pull sysfs fix from Al Viro:
 "Get rid of lockdep false positives around sysfs/overlayfs

  syzbot has uncovered a class of lockdep false positives for setups
  with sysfs being one of the backing layers in overlayfs. The root
  cause is that of->mutex allocated when opening a sysfs file read-only
  (which overlayfs might do) is confused with of->mutex of a file opened
  writable (held in write to sysfs file, which overlayfs won't do).

  Assigning them separate lockdep classes fixes that bunch and it's
  obviously safe"

27fd80851d Misc x86 fixes:
- Follow up fixes for the BHI mitigations code.
 
  - Fix !SPECULATION_MITIGATIONS bug not turning off

  - Work around an APIC emulation bug when the kernel is built with
    Clang and run as a SEV guest.
 
  - Follow up x86 topology fixes.
 
 Note that there's minor cleanups included in the BHI fixes,
 which we'd normally delay to the next merge window, but the
 BHI mitigations code is new and will be backported widely,
 so we thought it would be better to have a unified codebase
 at this stage. (Let me know if that assumption is wrong and
 I'll rebase it.)

16b52bbee4 kernfs: annotate different lockdep class for of->mutex of writable files
The writable file /sys/power/resume may call vfs lookup helpers for
arbitrary paths and readonly files can be read by overlayfs from vfs
helpers when sysfs is a lower layer of overalyfs.

To avoid a lockdep warning of circular dependency between overlayfs
inode lock and kernfs of->mutex, use a different lockdep class for
writable and readonly kernfs files.

3f10048973 bcachefs: Disable merges from interior update path
There's been a bug in the btree write buffer where it wasn't triggering
btree node merges - and leaving behind a bunch of nearly empty btree
nodes.

Then during journal replay, when updates to the backpointers btree
aren't using the btree write buffer (because we require synchronization
with journal replay), we end up doing those merges all at once.

Then if it's the interior update path running them, we deadlock because
those run with the highest watermark.

There's no real need for the interior update path to be doing btree node
merges; other code paths can handle that at lower watermarks.

thus can trigger a resize; thus we need to not retain direct pointers

c0297e7dd5 ata: libata-core: Allow command duration limits detection for ACS-4 drives
Even though the command duration limits (CDL) feature was first added
in ACS-5 (major version 12), there are some ACS-4 (major version 11)
drives that implement CDL as well.

IDENTIFY_DEVICE, SUPPORTED_CAPABILITIES, and CURRENT_SETTINGS log pages
are mandatory in the ACS-4 standard so it should be safe to read these
log pages on older drives implementing the ACS-4 standard.

Commit 0c76106cb9 ("scsi: sd: Fix TCG OPAL unlock on system resume")
incorrectly handles failures of scsi_resume_device() in
ata_scsi_dev_rescan(), leading to a double call to
spin_unlock_irqrestore() to unlock a device port. Fix this by redefining
the goto labels used in case of errors and only unlock the port
scsi_scan_mutex when scsi_resume_device() fails.

678e14c772 SoC fixes for 6.9
The device tree changes this time are all for NXP i.MX platforms, addressing
 issues with clocks and regulators on i.MX7 and i.MX8.
 
 The old OMAP2 based Nokia N8x0 tablet get a couple of code fixes for
 regressions that came in.
 
 The ARM SCMI and FF-A firmware interfaces get a couple of minor
 bug fixes.
 
 A regression fix for RISC-V cache management addresses a problem with
 probe order on Sifive cores.
