Subject: [PATCH 35/36] net/mac80211,rcu: convert call_rcu(work_free_rcu) to kfree_rcu()
Date: Fri, 18 Mar 2011 12:14:15 +0800 [thread overview]
Message-ID: <4D82DC17.2090106@cn.fujitsu.com> (raw)
The rcu callback work_free_rcu() just calls a kfree(),
so we use kfree_rcu() instead of the call_rcu(work_free_rcu).
