From e4e739131ac93d373cd2d2fd92820a6a39115ba5 Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Tue, 6 Jun 2017 23:22:03 +0800 Subject: blk-mq: introduce blk_mq_unquiesce_queue blk_mq_start_stopped_hw_queues() is used implictly as counterpart of blk_mq_quiesce_queue() for unquiescing queue, so we introduce blk_mq_unquiesce_queue() and make it as counterpart of blk_mq_quiesce_queue() explicitly. This function is for improving the current quiescing mechanism in the following patches.
