[PATCH tip/core/rcu 74/86] nfs,rcu: convert call_rcu(nfs_free_delegation_callback) to kfree_rcu()

From: Paul E. McKenney
Date: Sun May 01 2011 - 09:28:07 EST


From: Lai Jiangshan <laijs@xxxxxxxxxxxxxx>

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