Subject: [PATCH 07/36] net,rcu: convert call_rcu(ip_mc_list_reclaim) to kfree_rcu()
Date: Fri, 18 Mar 2011 11:44:08 +0800	[thread overview]
Message-ID: <4D82D508.5080901@cn.fujitsu.com> (raw)
In-Reply-To: <4D82D3FF.2080303@cn.fujitsu.com>



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