Subject: [PATCH 28/36] net,rcu: convert call_rcu(phonet_device_rcu_free) to kfree_rcu()
Date: Fri, 18 Mar 2011 12:09:03 +0800 [thread overview]
Message-ID: <4D82DADF.4010802@cn.fujitsu.com> (raw)
The rcu callback phonet_device_rcu_free() just calls a kfree(),
so we use kfree_rcu() instead of the call_rcu(phonet_device_rcu_free).
