Subject: [PATCH 03/10] nfsd: simplify nfs4_put_deleg_lease calls
Date: Mon, 19 Mar 2018 10:36:27 -0400	[thread overview]
Message-ID: <1521470194-24840-4-git-send-email-bfields@redhat.com> (raw)
In-Reply-To: <1521470194-24840-1-git-send-email-bfields@redhat.com>

From: "J. Bruce Fields" <bfields@redhat.com>

Every single caller gets the file out of the delegation, so let's do
that once in nfs4_put_deleg_lease.

Plus we'll need it there for other reasons.
