From f660174e8bcdb2bf99129f9f7c86e5fc0e830f85 Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Tue, 6 Jun 2017 23:22:04 +0800 Subject: blk-mq: use the introduced blk_mq_unquiesce_queue() blk_mq_unquiesce_queue() is used for unquiescing the queue explicitly, so replace blk_mq_start_stopped_hw_queues() with it. For the scsi part, this patch takes Bart's suggestion to switch to block quiesce/unquiesce API completely.
