From mboxrd@z Thu Jan 1 00:00:00 1970 From: Lai Jiangshan Subject: [PATCH 15/36] net,rcu: convert call_rcu(ipv6_mc_socklist_reclaim) to kfree_rcu() Date: Fri, 18 Mar 2011 12:00:50 +0800 Message-ID: <4D82D8F2.5020208@cn.fujitsu.com> Mime-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit To: "Paul E. McKenney" , Ingo Molnar , "David S. Miller" , Alexey Kuznetsov , "Pekka Savola (ipv6)" Return-path: Received: from cn.fujitsu.com ([222.73.24.84]:64588 "EHLO song.cn.fujitsu.com" rhost-flags-OK-FAIL-OK-OK) by vger.kernel.org with ESMTP id S932176Ab1CRD7F (ORCPT ); Thu, 17 Mar 2011 23:59:05 -0400 Sender: netdev-owner@vger.kernel.org List-ID: The rcu callback ipv6_mc_socklist_reclaim() just calls a kfree(), so we use kfree_rcu() instead of the call_rcu(ipv6_mc_socklist_reclaim).
