ext4: fix unjournaled inode bitmap modification (2012-10-28 22:24:57 -0400)
----------------------------------------------------------------
This fixes the root cause of the ext4 data corruption bug which raised
a ruckus on LWN, Phoronix, and Slashdot. This bug only showed up when
non-standard mount options (journal_async_commit and/or
journal_checksum) were enabled, and when the file system was not
cleanly unmounted, but the root cause was the inode bitmap
modifications was not being properly journaled. This could
potentially lead to minor file system corruptions (pass 5 complaints
with the inode allocation bitmap) after an unclean shutdown under the
wrong/unlucky workloads, but it turned into major failure if the
journal_checksum and/or jouaral_async_commit was enabled.
