From 7b1cffa8c90269dc3dc721d084d1e0d742d87c31 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Sun, 13 Apr 2008 22:29:37 -0700 Subject: [PATCH] [NETNS][DCCPV4]: Move the dccp_v4_ctl_sk on the struct net. And replace all its usage with init_net's socket. Signed-off-by: Pavel Emelyanov Acked-by: Arnaldo Carvalho de Melo Signed-off-by: David S.
