[PATCH 00/50] Remove the request pointer from struct scsi_cmnd

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.
