Subject: nfs,rcu: convert call_rcu(nfs_free_delegation_callback) to kfree_rcu()
X-Git-Tag: firefly_0821_release~7613^2~1000^2~6
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=26f04dde681c6a48b2bacfc5fe01fef204419b0c;p=firefly-linux-kernel-4.4.55.git

nfs,rcu: convert call_rcu(nfs_free_delegation_callback) to kfree_rcu()

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).
