Subject: [PATCH v4 08/36] scsi: scsi_dh: Convert to scsi_exec_req
Date: Sun, 16 Oct 2022 14:59:18 -0500	[thread overview]
Message-ID: <20221016195946.7613-9-michael.christie@oracle.com> (raw)
In-Reply-To: <20221016195946.7613-1-michael.christie@oracle.com>

scsi_execute* is going to be removed. Convert to scsi_exec_req so
we pass all args in a scsi_exec_args struct.
