This reverts commit a2673b6e. Kinglong Mee reports a memory leak with that patch, and Jan Kara confirms: "Thanks for report! You are right that my patch introduces a race between fsnotify kthread and fsnotify_destroy_group() which can result in leaking inotify event on group destruction. I haven't yet decided whether the right fix is not to queue events for dying notification group (as that is pointless anyway) or whether we should just fix the original problem differently... Whenever I look at fsnotify code mark handling I get lost in the maze of locks, lists, and subtle differences between how different notification systems handle notification marks :( I'll think about it over night" and after thinking about it, Jan says: "OK, I have looked into the code some more and I found another relatively simple way of fixing the original oops. It will be IMHO better than trying to fixup this issue which has more potential for breakage. I'll ask Linus to revert the fsnotify fix he already merged and send a new fix" Reported-by:
