How can you print out sense_key and sense code here? sense code will
not be copied to pre_req->sense. you should directly use
scsi_request->sense or let pre_req->sense point to scsi_request->sense.

You update the new version patch so quickly. In another word, I am
wondering if you tested your patch before submitting?
