Subject[PATCH tip/core/rcu 74/86] nfs,rcu: convert call_rcu(nfs_free_delegation_callback) to kfree_rcu()
Date
From: Lai Jiangshan <laijs@cn.fujitsu.com>

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).
