Subject[PATCH tip/core/rcu 08/47] tcm_fc: Convert call_rcu() to kfree_rcu(), drop ft_tport_rcu_free()
Date
From: "Paul E. McKenney" <paul.mckenney@linaro.org>

The call_rcu() in ft_tport_delete() invokes ft_tport_rcu_free(),
which just does a kfree(). So convert the call_rcu() to kfree_rcu(),
allowing ft_tport_rcu_free() to be eliminated.
