Subject: [PATCH 2/6] SCSI: use blk_mq_run_hw_queues() in scsi_kick_queue()
Date: Wed, 12 Jul 2017 02:20:59 +0800	[thread overview]
Message-ID: <20170711182103.11461-3-ming.lei@redhat.com> (raw)
In-Reply-To: <20170711182103.11461-1-ming.lei@redhat.com>

Now SCSI won't stop queue, and not necessary to use
blk_mq_start_hw_queues(), so switch to blk_mq_run_hw_queues()
instead.
