FYI, I've updated the patch a bit in my tree to always set e->tag to SIMPLE_QUEUE_TAG. The rationale for that is that we actually never set MSG_ORDERED_TAG for other drivers since 2010, and fixing this up properly in this driver makes it conflict less with my patch series to fix up more mess in this area.
Updated patch below: --- From: Hannes Reinecke <[email protected]> Subject: vmw_pvscsi: fixup tagging The request (and SCSI command) tag is the tag number assigned by the generic block-tagging code, not the SCSI-II tag messages. Those are represented by the device flags 'tagged_supported', 'simple_tags', and 'ordered_tags'. (The SCSI midlayer doesn't use HEAD_OF_QUEUE tags). So fixup vmw_pvscsi to assign the correct tag type.
