Please send the reproducer.  Note that if it requries a maliciously
fuzzed file system, we consider this to be a minor bug (especially if
the maliciously file system would be fixed when the system
administrator runs fsck on the file system first), and not "security"
issue, so feel free to just send it to the list.

Cheers,
