Shouldn't symbolic names be introduced for these numeric constants?
Although there is more code in the SCSI core that compares ASC / ASCQ
values with numeric constants, I think we need symbolic names for these
constants to make code like the above easier to read. There is already
a header file for definitions that come directly from the SCSI standard
and that is used by both SCSI initiator and SCSI target code:
<scsi/scsi_proto.h>.

Thanks,

Bart.
