From ea82edf704f6bf3c3a51d0dbee816c5bbc6d3974 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Fri, 21 Mar 2008 04:10:53 -0700 Subject: [PATCH] [NETNS][IPV6] mcast - fix compilation warning when procfs is not compiled in When CONFIG_PROC_FS=no, the out_sock_create label is not used because the code using it is disabled and that leads to a warning at compile time. This patch fix that by making a specific function to initialize proc for igmp6, and remove the annoying CONFIG_PROC_FS sections in init/exit function.
