Subject: [PATCH 05/11] NFSv4: Ignore NFS_INO_REVAL_FORCED in nfs4_proc_access
Date: Mon,  4 Jun 2018 18:31:23 -0400	[thread overview]
Message-ID: <20180604223129.121477-5-trond.myklebust@hammerspace.com> (raw)
In-Reply-To: <20180604223129.121477-4-trond.myklebust@hammerspace.com>

If we hold a delegation, we don't need to care about whether or not
the inode attributes are up to date. We know we can cache the results
of this call regardless.
