Hi Jens, this series simplifies teardown for most block drivers. Right now they also have to call blk_cleanup_queue after calling del_gendisk, making the teardown process rather confusing. Instead this series records if the request_queue is owned by the gendisk, which is always the case except for scsi and dasd or queues without a gendisk at all, and then does the entire teardown in del_gendisk. Note that while intended or 5.20, this series is generated against the block-5.19 branch as that contains fixes in this area that haven't made it to the for-5.10/block branch yet.
