From 025cea99db3fb110ebc8ede5ff647833fab9574f Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Tue, 15 Mar 2011 17:56:10 +0800 Subject: [PATCH] cgroup,rcu: convert call_rcu(__free_css_id_cb) to kfree_rcu() The rcu callback __free_css_id_cb() just calls a kfree(), so we use kfree_rcu() instead of the call_rcu(__free_css_id_cb).
