If anyone has any objections, please let me know. ------------------ From: Trond Myklebust commit dbb21c25a35a71baf413f5176f028ee11b88cfbc upstream. 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.
