Message-ID: <47F0D665.9010807@openvz.org>
Date: Mon, 31 Mar 2008 16:17:41 +0400
From: Pavel Emelyanov <xemul@...nvz.org>
To: David Miller <davem@...emloft.net>
CC: Linux Netdev List <netdev@...r.kernel.org>, devel@...nvz.org
Subject: [PATCH net-2.6.26 4/6][SOCK][NETNS]: Register sockstat(6) files in
each net.
Currently they live in init_net only, but now almost all the info
they can provide is available per-net.
Signed-off-by: Pavel Emelyanov <xemul@...nvz.org>
