From 94911fe31710e355e9fcac8b1a7eb36c4953f36b Mon Sep 17 00:00:00 2001 From: Benjamin Thery Date: Wed, 5 Mar 2008 10:45:36 -0800 Subject: [PATCH] [NETNS][IPV6] Move sysctl initialization later on in the IPv6 init sequence This patch moves initialization of IPv6 sysctl stuff at the end of IPv6 initialization. This will be helpful for network namespaces where some sysctl entries depend on per-namespace variables, that need to be allocated and initialized before they are referenced by sysctl.
