[PATCH tip/core/rcu 39/86] net,rcu: convert call_rcu(in6_dev_finish_destroy_rcu) to kfree_rcu()

From: Paul E. McKenney
Date: Sun May 01 2011 - 09:33:01 EST


From: Lai Jiangshan <laijs@xxxxxxxxxxxxxx>

The rcu callback in6_dev_finish_destroy_rcu() just calls a kfree(),
so we use kfree_rcu() instead of the call_rcu(in6_dev_finish_destroy_rcu).
