From c29a0bc4dfc4d833eb702b1929cec96a3eeb9f7a Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Mon, 31 Mar 2008 19:41:46 -0700 Subject: [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.
