Subject: [PATCH v2 07/10] NFS: Keep module parameters in the generic NFS client
Date: Mon, 30 Jul 2012 16:05:22 -0400 [thread overview]
Message-ID: <1343678725-8659-8-git-send-email-bjschuma@netapp.com> (raw)
In-Reply-To: <1343678725-8659-1-git-send-email-bjschuma@netapp.com>
From: Bryan Schumaker <bjschuma@netapp.com>
Otherwise we break backwards compatibility when v4 becomes a modules.
