From fa81c0e1d2d2176f1136c72c080c9ea4a98be347 Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Fri, 18 Mar 2011 11:39:43 +0800 Subject: [PATCH] net,rcu: convert call_rcu(free_dm_hw_stat) to kfree_rcu() The rcu callback free_dm_hw_stat() just calls a kfree(), so we use kfree_rcu() instead of the call_rcu(free_dm_hw_stat).
