From 5d6d480908300a0c0b3be8b58567dfcef62c83a5 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Fri, 7 Nov 2008 22:52:34 -0800 Subject: net: fib_rules ordering fixes. We need to setup the network namespace state before we register the notifier. Otherwise if a network device is already registered we get a nasty NULL pointer dereference. Signed-off-by: Eric W.
