--- Comment #3 from Theodore Tso (tytso@mit.edu) ---
When reporting these sorts of syzkaller bugs, please include the file system
image that was mounted in the VM.

The official upstream syzkaller has a way where you can download it from their
web interface.  The problem with people running forked copies of syzkallers are
(a) often this is a duplicate of a bug already reported by the upstrea/official
syzkaller, and (b) without the web interface, looking at these bugs are much
more difficult.

Also note that if the file system image is corrupted (which is often the case
with Syzkaller), addressing these issues are a best efforts basis by the ext4
developers.   Some company is going to fund an engineer to work on this on
official work time.  Volunteers who have time on weekends or late at night
can't be expected to work these sorts of issues on anything other than a "best
efforts" basis.
