commit 6e73e92b15 upstream.
When running an nfs stress test, I see quite a few cached replies that
don't match up with the actual request. The first comment in
replay_matches_cache() makes sense, but the code doesn't seem to
match... fix it.
This isn't exactly a bugfix, as the server isn't required to catch every
case of a false retry. So, we may as well do this, but if this is
fixing a problem then that suggests there's a client bug.
Fixes: 53da6a53e1 ("nfsd4: catch some false session retries")
