Miklos Szeredi 0d6ec079d6 fsnotify: pin both inode and vfsmount mark ... We may fail to pin one of the marks in fsnotify_prepare_user_wait() when dropping the srcu read lock, resulting in use after free at the next iteration. Solution is to store both marks in iter_info instead of just the one we'll be sending the event for.
