From 3680453c8be54fff0d23fdf33e8961a48e1f2cd6 Mon Sep 17 00:00:00 2001 From: Eric Dumazet <dada1@cosmosbay.com> Date: Wed, 19 Nov 2008 14:25:35 -0800 Subject: [PATCH] net: af_packet should update its inuse counter This patch is a preparation to namespace conversion of /proc/net/protocols In order to have relevant information for PACKET protocols, we should use sock_prot_inuse_add() to update a (percpu and pernamespace) counter of inuse sockets.
