Ian Kent 25f54d08f1 autofs: fix wait name hash calculation in autofs_wait() ... There's a mistake in commit 2be7828c9f ("get rid of autofs_getpath()") that affects kernels from v5.13.0, basically missed because of me not fully testing the change for Al. The problem is that the hash calculation for the wait name qstr hasn't been updated to account for the change to use dentry_path_raw(). This prevents the correct matching an existing wait resulting in multiple notifications being sent to the daemon for the same mount which must not occur. The problem wasn't discovered earlier because it only occurs when multiple processes trigger a request for the same mount concurrently so it only shows up in more aggressive testing.
