Subject: [PATCH v4 02/20] NFSv4.1: Don't check delegations that are already marked as revoked
Date: Thu, 15 Sep 2016 12:45:42 -0400 [thread overview]
Message-ID: <1473957960-10001-3-git-send-email-trond.myklebust@primarydata.com> (raw)
In-Reply-To: <1473957960-10001-2-git-send-email-trond.myklebust@primarydata.com>
If the delegation has been marked as revoked, we don't have to test
it, because we should already have called FREE_STATEID on it.
