From 8e141f9eb803e209714a80aa6ec073893f94c526 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 29 Sep 2021 09:12:40 +0200 Subject: block: drain file system I/O on del_gendisk Instead of delaying draining of file system I/O related items like the blk-qos queues, the integrity read workqueue and timeouts only when the request_queue is removed, do that when del_gendisk is called. This is important for SCSI where the upper level drivers that control the gendisk are separate entities, and the disk can be freed much earlier than the request_queue, or can even be unbound without tearing down the queue.
