Message-ID: <478B5EDA.4000407@openvz.org>
Date: Mon, 14 Jan 2008 16:08:42 +0300
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-2.6.25 2/4][NETNS][RAW]: Make /proc/net/raw(6) show per-namespace
socket list.
Pull the struct net pointer up to the showing functions
to filter the sockets depending on their namespaces.
Signed-off-by: Pavel Emelyanov <xemul@...nvz.org>
