Subject: [GIT PULL] ext4 changes for 6.1
The following changes since commit a078dff870136090b5779ca2831870a6c5539d36:
ext4: fixup possible uninitialized variable access in ext4_mb_choose_next_group_cr1() (2022-09-26 13:21:05 -0400)

ext4: fix potential out of bound read in ext4_fc_replay_scan() (2022-09-30 23:46:54 -0400)
----------------------------------------------------------------
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.
