Message-ID: <47F0D511.2090403@openvz.org>
Date: Mon, 31 Mar 2008 16:12:01 +0400
From: Pavel Emelyanov <xemul@...nvz.org>

Subject: [PATCH net-2.6.26 2/6][SOCK][NETNS]: Add a struct net argument to
sock_prot_inuse_add and _get.
This counter is about to become per-proto-and-per-net, so we'll need
two arguments to determine which cell in this "table" to work with.
All the places, but proc already pass proper net to it - proc will be
tuned a bit later.
Some indentation with spaces in proc files is done to keep the file
coding style consistent.
