That is really gross. I have explained many times in detail on the dm-devel list why that blk_mq_delay_run_hw_queue() call is necessary. So I think it is wrong if you remove it. Isn't the responsibility of you as the device mapper kernel maintainer to avoid regressions instead of introducing regressions? Bart.
