--- Comment #4 from Theodore Tso ( ---
This bug is addressed by these two commits:

jbd2: don't mark block as modified if the handle is out of credits

ext4: avoid running out of journal credits when appending to an inline file

This bug can be triggered without needing a specially crafted file system
(although, of course, the inline_data feature has to be enabled in the file
system --- which is currently not enabled by the default).
