From 94aec08ea426903a3fb3cafd4d8b900cd50df702 Mon Sep 17 00:00:00 2001 From: Brian Haley Date: Mon, 18 Sep 2006 00:05:22 -0700 Subject: [NETFILTER]: Change tunables to __read_mostly Change some netfilter tunables to __read_mostly. Also fixed some incorrect file reference comments while I was in there. (this will be my last __read_mostly patch unless someone points out something else that needs it) Signed-off-by: Brian Haley Acked-by: Patrick McHardy Signed-off-by: David S.
