  ext4: properly sync file size update after O_SYNC direct IO (2023-10-31 20:20:55 -0400)

Cleanup ext4's multi-block allocator, including adding some unit
tests, as well as cleaning how we update the backup superblock after
online resizes or updating the label or uuid.

Optimize handling of released data blocks in ext4's commit machinery
to avoid a potential lock contention on s_md_lock spinlock.

Fix a number of ext4 bugs:

 - fix race between writepages and remount
 - fix racy may inline data check in dio write
 - add missed brelse in an error path in update_backups
 - fix umask handling when ACL support is disabled
 - fix lost EIO error when a journal commit races with a fsync of the
 - fix potential improper i_size when there is a crash right after an
   O_SYNC direct  write.
 - check extent node for validity before potentially using what might
   be an invalid pointer
 - fix potential stale data exposure when writing to an unwritten extent
   and the file system is nearly out of space
 - fix potential accounting error around block reservations when writing
   partial delayed allocation writes to a bigalloc cluster
 - avoid memory allocation failure when tracking partial delayed allocation
   writes to a bigalloc cluster
 - fix various debugging print messages
