This patch series definitely is an alternative for blk-mq/scsi-mq. And as you know my approach can be extended easily to the legacy SCSI core by adding blk_queue_enter() / blk_queue_exit() calls where necessary in the legacy block layer. I have not done this because the bug report was against scsi-mq and not against the legacy SCSI core. Additionally, since the legacy block layer and SCSI core are on their way out I did not want to spend time on modifying these. Bart.
