Subject: [PATCH 2/6] SCSI: use blk_mq_run_hw_queues() in scsi_kick_queue()
Date: Sat, 15 Jul 2017 07:15:57 +0800	[thread overview]
Message-ID: <20170714231601.14444-3-ming.lei@redhat.com> (raw)
In-Reply-To: <20170714231601.14444-1-ming.lei@redhat.com>

Now SCSI won't stop queue at all, and not necessary to use
blk_mq_start_hw_queues() to clear the state of 'stopped',
so switch to blk_mq_run_hw_queues() instead.
