Subject: [PATCH 4/9] NFS: Don't revalidate the file on close if we hold a delegation
Date: Sat, 17 Dec 2016 13:27:06 -0500	[thread overview]
Message-ID: <20161217182711.10643-5-trond.myklebust@primarydata.com> (raw)
In-Reply-To: <20161217182711.10643-4-trond.myklebust@primarydata.com>

If we're holding a delegation, we can skip sending the close-to-open
GETATTR until we're returning that delegation.
