From 9c28ca4ff8bad7486182291a55b4f67a70af718d Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Wed, 8 Mar 2017 00:09:59 -0800 Subject: [PATCH] target: Drop pointless tfo->check_stop_free check All in-tree fabric drivers provide a tfo->check_stop_free(), so there is no need to do the extra check within existing transport_cmd_check_stop_to_fabric() code. Just to be sure, add a check in target_fabric_tf_ops_check() to notify any out-of-tree drivers that might be missing it.
