From dbb21c25a35a71baf413f5176f028ee11b88cfbc Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 1 Apr 2013 14:27:29 -0400 Subject: [PATCH] NFSv4: Handle NFS4ERR_DELAY and NFS4ERR_GRACE in nfs4_lock_delegation_recall A server shouldn't normally return NFS4ERR_GRACE if the client holds a delegation, since no conflicting lock reclaims can be granted, however the spec does not require the server to grant the lock in this instance.
