From 6f8191fdf41d3a53cc1d63fe2234e812c55a0092 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 19 Jun 2022 08:05:51 +0200 Subject: block: simplify disk shutdown Set the queue dying flag and call blk_mq_exit_queue from del_gendisk for all disks that do not have separately allocated queues, and thus remove the need to call blk_cleanup_queue for them. Rename blk_cleanup_disk to blk_mq_destroy_queue to make it clear that this function is intended only for separately allocated blk-mq queues. This saves an extra queue freeze for devices without a separately allocated queue.
