Subject: [PATCH 12/36] jbd2,rcu: convert call_rcu(free_devcache) to kfree_rcu()
Date: Fri, 18 Mar 2011 11:58:08 +0800	[thread overview]
Message-ID: <4D82D850.6090702@cn.fujitsu.com> (raw)



The rcu callback free_devcache() just calls a kfree(),
so we use kfree_rcu() instead of the call_rcu(free_devcache).
