Subject: [PATCH 4/8] NFS: Assume cred is pinned by open context in I/O requests
Date: Mon, 10 Feb 2020 14:13:41 -0500	[thread overview]
Message-ID: <20200210191345.557460-5-trond.myklebust@hammerspace.com> (raw)
In-Reply-To: <20200210191345.557460-4-trond.myklebust@hammerspace.com>

In read/write/commit, we should be able to assume that the cred is
pinned by the open context.
