[PATCH tip/core/rcu 67/86] net,rcu: convert call_rcu(phonet_device_rcu_free) to kfree_rcu()

From: Paul E. McKenney
Date: Sun May 01 2011 - 09:27:45 EST


From: Lai Jiangshan <laijs@xxxxxxxxxxxxxx>

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).
