From 9801c60e99ed76c5730fb290c00bfad12a419972 Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Fri, 18 Mar 2011 12:05:22 +0800 Subject: security,rcu: Convert call_rcu(sel_netnode_free) to kfree_rcu() The rcu callback sel_netnode_free() just calls a kfree(), so we use kfree_rcu() instead of the call_rcu(sel_netnode_free).
