| |
3.8-stable review patch. If anyone has any objections, please let me know.

From: Trond Myklebust <Trond.Myklebust@netapp.com>
commit 8b6cc4d6f841d31f72fe7478453759166d366274 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 open in this instance
