  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.
