For crying out loud... Seeing that it has


in it and seeing that MAINTAINERS has

M: Jan Kara <jack@xxxxxxxx>
S: Maintained
F: Documentation/filesystems/udf.rst
F: fs/udf/

"[syzbot] WARNING in __brelse" says nothing beyond "it's probably about

You, OTOH, have that information from the very beginning...
