Great bug report!  It's really neat that you're doing this.  ;)

You might be able to find a FS-agnostic fuzzer by doing a search for
'filesystem fuzzer'.  It's not an area that I've explored much myself, so I'm
just throwing that out there.  e.g.
https://ext4.wiki.kernel.org/index.php/Filesystem_Testing_Tools/mangle.c

Nice work!
