Subject: [PATCH v3 00/51] Remove the request pointer from struct scsi_cmnd
Date: Sun, 23 May 2021 20:08:05 -0700 [thread overview]
Message-ID: <20210524030856.2824-1-bvanassche@acm.org> (raw)
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 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.
