From 4c8e5447465c9cf92ff1c5e36e8f316b69d46aa8 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 22 Sep 2016 13:38:55 -0400 Subject: [PATCH] NFSv4.1: Don't check delegations that are already marked as revoked 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.
