Message-Id: <1206695338-5947-6-git-send-email-den@openvz.org>
Date: Fri, 28 Mar 2008 12:08:53 +0300
From: "Denis V. Lunev" <den@...nvz.org>
To: davem@...emloft.net
Cc: netdev@...r.kernel.org, containers@...ts.osdl.org,
"Denis V. Lunev" <den@...nvz.org>
Subject: [PATCH 6/11 net-2.6.26] [INET]: Let inet_csk_ctl_sock_create return sock rather than socket.
All upper protocol layers are already use sock internally.
Signed-off-by: Denis V. Lunev <den@...nvz.org>
