  jbd2: fix a potential race while discarding reserved buffers after an abort (2022-04-21 14:21:30 -0400)

----------------------------------------------------------------
Fix some syzbot-detected bugs, as well as other bugs found by I/O
injection testing.  Change ext4's fallocate to update consistently
drop set[ug]id bits when an fallocate operation might possibly change
the user-visible contents of a file.  Also, improve handling of
potentially invalid values in the the s_overhead_cluster superblock
field to avoid ext4 returning a negative number of free blocks.
