Subject: [PATCH 08/11] nfsd4: separate callback change and callback probe
Date: Thu, 21 Oct 2010 12:20:15 -0400 [thread overview]
Message-ID: <1287678018-9266-9-git-send-email-bfields@redhat.com> (raw)
In-Reply-To: <1287678018-9266-1-git-send-email-bfields@redhat.com>
Only one of the nfsd4_callback_probe callers actually cares about
changing the callback information.
