[PATCH tip/core/rcu 15/28] scsi,rcu: Convert call_rcu(fc_rport_free_rcu) to kfree_rcu()

From: Paul E. McKenney
Date: Wed Jun 08 2011 - 15:35:30 EST


From: Lai Jiangshan <laijs@xxxxxxxxxxxxxx>

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