From a5ea6169f294bc33a762f7c1c240e3ac0f045f9e Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Mon, 12 Feb 2007 11:11:06 -0800 Subject: [NETFILTER]: nf_log: use rcu_assign_pointer for RCU protected pointer Also replace synchronize_net() calls by synchronize_rcu() since the RCU protected data is also used for sysfs.
