The folk at t10.org slipped this innocuous looking addition into sam5r04 section 5.3.1 on status codes. "Sense data may be delivered in the buffer defined by the Sense Data argument of the Execute Command procedure call (see 5.1) for any status code." Previously sense data was only valid for status CHECK_CONDITION [0x2] (and the obsolete COMMAND_TERMINATED [0x22]). The quoted section in the previous paragraph means that sense data could arrive with any status code. And now with draft sbc3r22 there is an example: status=GOOD, sense_key=COMPLETED (recently added) additional_sense_qualifier="INSPECT REFERRALS SENSE DESCRIPTORS". Referrals are new and explained in sbc3r22. IMO only a very small audience would be interested in them. However it does indicate a new trend. So the question for the Linux scsi subsystem is does it (or can it without many changes) convey "non CHECK_CONDITION" sense data back up from an initiator (LLD) to code that might care?
