From 2834a6386b86a5dd20380aadb01897c525448aa7 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Sun, 19 Aug 2012 10:16:10 +0000 Subject: [PATCH] netfilter: nf_conntrack: remove unnecessary RTNL locking Locking the rtnl was added to nf_conntrack_l{3,4}_proto_unregister() for walking the network namespace list. This is not done anymore since we have proper namespace support in the protocols now, so we don't need to take the RTNL anymore.
