Subject: [PATCH 13/16] nfsd4: minor nfs4_setlease cleanup
Date: Wed, 17 Jul 2013 16:50:14 -0400 [thread overview]
Message-ID: <1374094217-31493-15-git-send-email-bfields@redhat.com> (raw)
In-Reply-To: <1374094217-31493-1-git-send-email-bfields@redhat.com>
From: "J. Bruce Fields" <bfields@redhat.com>
As far as I can tell, this list is used only under the state lock, so we
may as well do this in the simpler order.
