Hi Martin, This patch series increases IOPS by 5% on my test setup in a single-threaded test with queue depth 1 on top of the scsi_debug driver. Please consider this patch series for kernel v5.16. Thanks, Bart. Changes compared to v1: - Inserted the SUBMITTED_BY_ prefix in front of the enumeration constants introduced in patch 1. - Reworked the fas216 patch such that the scsi_done pointer is preserved. - Moved some SCSI core changes from the start of this series to the end to improve bisectability of this series. - Added explicit initialization of the new "submitter" member variable instead of relying on implicit initialization. - Added Reviewed-by/Acked-by tags.
