From 3acb458c32293405cf68985b7b3ac5dc0a5e7929 Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Fri, 18 Mar 2011 12:11:07 +0800 Subject: [PATCH] security,rcu: convert call_rcu(user_update_rcu_disposal) to kfree_rcu() The rcu callback user_update_rcu_disposal() just calls a kfree(), so we use kfree_rcu() instead of the call_rcu(user_update_rcu_disposal).
