Miklos Szeredi f130790f1a fanotify: fix false positive on permission events ...

commit 7746e3bd4c upstream.

fsnotify_get_mark_safe() may return false for a mark on an unrelated group,
which results in bypassing the permission check.

Fix by skipping over detached marks that are not in the current group.
