Jan Kara b3a0066005 dnotify: Handle errors from fsnotify_add_mark_locked() in fcntl_dirnotify() ... fsnotify_add_mark_locked() can fail but we do not check its return value. This didn't matter before commit 9dd813c15b "fsnotify: Move mark list head from object into dedicated structure" as none of possible failures could happen for dnotify but after that commit -ENOMEM can be returned. Handle this error properly in fcntl_dirnotify() as otherwise we just hit BUG_ON(dn_mark->dn) in dnotify_free_mark().
