Date: Thu, 27 Mar 2008 11:07:00 +0300 From: Pavel Emelyanov <xemul@...nvz.org> To: David Miller <davem@...emloft.net> CC: Linux Netdev List <netdev@...r.kernel.org>, Eric Dumazet <dada1@...mosbay.com>, devel@...nvz.org Subject: [PATCH net-2.6.26 1/6][NETNS][SOCK]: Add net parameter to sock_prot_inuse_(add|get). It will be used in netnsizated versions of these calls only. The net passed to then is either get from a sock, or is available int place, with two exceptions - the "sockstat" and "sockstat6" proc files use init_net by now.
