From 68ec3b819a5d600a4ede8b596761dccac9f39ebc Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 21 Oct 2021 08:06:05 +0200 Subject: scsi: add a scsi_alloc_request helper Add a new helper that calls blk_get_request and initializes the scsi_request to avoid the indirect call through ->.initialize_rq_fn. Note that this makes the pktcdvd driver depend on the SCSI core, but given that only SCSI devices support SCSI passthrough requests that is not a functional change.
