From 89918fc270bb77cb1a0703f0ea566a692b32e324 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Thu, 10 Jan 2008 02:49:34 -0800 Subject: [PATCH] [NETNS][IPV6]: Make the ipv6 sysctl to be a netns subsystem. The initialization of the sysctl for the ipv6 protocol is changed to a network namespace subsystem. That means when a new network namespace is created the initialization function for the sysctl will be called. That do not change the behavior of the sysctl in case of the kernel with the network namespace disabled. Signed-off-by: Daniel Lezcano Signed-off-by: David S.
