Message-Id: <20110312.152531.39181803.davem@davemloft.net>
Date:	Sat, 12 Mar 2011 15:25:31 -0800 (PST)
From:	David Miller <davem@...emloft.net>
To:	netdev@...r.kernel.org
Subject: [PATCH 3/25] xfrm: Eliminate "fl" and "pol" args to
 xfrm_bundle_ok().


There is only one caller of xfrm_bundle_ok(), and that always passes these
parameters as NULL.
