From what I can see, the fix is working for new filesystem bugs: the filesystem(s) involved get added to the title and the recipients. One question: what happens to all the open bugs, like this one ("WARNING in do_mkdirat") that were reported before the syzbot fix? Are they going to be re-reported correctly? Perhaps any bug whose reproducer includes "syz_mount_image" and was reported before the date of this fix should be invalidated more aggressively than usual, so that it can be re-reported? - Eric
