Damien and I talked about this.

Since this patch only affects non-PT commands, what it this patch actually
solving?

Since for non-PT commands, sense data is not returned to the user.

So unless SCSI core does some specific handling based on the INFORMATION
field (and AFAICT, SCSI core only looks at SK/ASC/ASCQ), I can't see how
this patch can actually solve anything.

Kind regards,
Niklas
