When freeing permission events by fsnotify_destroy_event(), the warning WARN_ON(!list_empty(&event->list)); may falsely hit. This is because although fanotify_get_response() saw event->response set, there is nothing to make sure the current CPU also sees the removal of the event from the list. Add proper locking around the WARN_ON() to avoid the false warning.
