Subject: [PATCH v5 02/52] core: Use scsi_cmd_to_rq() instead of scsi_cmnd.request
Date: Mon, 9 Aug 2021 16:03:05 -0700 [thread overview]
Message-ID: <20210809230355.8186-3-bvanassche@acm.org> (raw)
In-Reply-To: <20210809230355.8186-1-bvanassche@acm.org>
Prepare for removal of the request pointer by using scsi_cmd_to_rq()
instead. Cast away constness where necessary when passing a SCSI command
pointer to scsi_cmd_to_rq(). This patch does not change any functionality.
