Hi Martin, This patch series implements the following two changes for all SCSI drivers: - Use blk_mq_rq_from_pdu() instead of the request member of struct scsi_cmnd since adding an offset to a pointer is faster than pointer indirection. - Remove the request pointer from struct scsi_cmnd. Please consider this patch series for kernel v5.14. Thanks, Bart. Changes compared to v2: - Added several more Acked-by tags. - Rebased this patch series. Changes compared to v2: - Added a patch for the aha1542 driver since a recent change introduced a scsi_cmnd.request dereference in that driver. - In patch 2, renamed a local variable in a macro from 'rq' into '__rq'. - Added several more Acked-by tags. Changes compared to v1: - Renamed blk_req() into scsi_cmd_to_rq(). - Added several Acked-by tags.
