From 6034f7e603cd2dae8ed9a1d8d2ccfeb6b5c48d73 Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Tue, 15 Mar 2011 18:07:57 +0800 Subject: [PATCH] security,rcu: Convert call_rcu(whitelist_item_free) to kfree_rcu() The rcu callback whitelist_item_free() just calls a kfree(), so we use kfree_rcu() instead of the call_rcu(whitelist_item_free).
