From a8076d8db98de6da61394b2e942320e4612643ac Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 17 Nov 2008 02:38:49 -0800 Subject: [PATCH] net: af_unix should update its inuse counter This patch is a preparation to namespace conversion of /proc/net/protocols In order to have relevant information for UNIX protocol, we should use sock_prot_inuse_add() to update a (percpu and pernamespace) counter of inuse sockets.
