In the JFS filesystem, right? <snip>
fs/jfs/jfs_debug.c | 2 ++
$ ./scripts/get_maintainer.pl fs/jfs/jfs_debug.c Dave Kleikamp <shaggy () kernel org> (odd fixer:JFS FILESYSTEM) jfs-discussion () lists sourceforge net (open list:JFS FILESYSTEM) linux-kernel () vger kernel org (open list) Any specific reason you didn't send this to the mailing list and developers who can review and apply this potential fix to the kernel tree? syzbot-reported issues are not really a new or exciting thing, we get loads of them every week (see the syzbot mailing list and summaries). What is good is for fixes like this one to be sent to us so that we can merge them for all to use. That is if anyone is actually using the JFS filesystem anymore, it is pretty obsolete. Are you using it? thanks, greg k-h
