Although there are various exported symbols in kernel/block/blk-settings.c that can be used to configure a request queue, users cannot utilize them as needed. For example, I want to change the timeout setting by calling blk_queue_rq_timeout(). Because 60 seconds is too long depending on the device. Therefore, we need a method for independent configuration for each host.
