Subject: [PATCH 7/8] NFS: Avoid referencing the cred twice in async rename/unlink
Date: Mon, 10 Feb 2020 14:13:44 -0500	[thread overview]
Message-ID: <20200210191345.557460-8-trond.myklebust@hammerspace.com> (raw)
In-Reply-To: <20200210191345.557460-7-trond.myklebust@hammerspace.com>

In both async rename and rename, we take a reference to the
cred in the call arguments.
