The one thing which I patently don't like is the ambivalence between DRIVER_SENSE and scsi_sense_valid(). What shall we do if only _one_ of them is set? IE what would be the correct way of action if DRIVER_SENSE is not set, but we have a valid sense code? Or the other way around? But more important, from a quick glance not all drivers set the DRIVER_SENSE bit; so for things like hpsa or smartpqi the sense code is never evaluated after this patchset. I _really_ would prefer to ditch the 'DRIVER_SENSE' bit, and rely on scsi_sense_valid() only.
