SAT-4(SCSI/ATA Translation Standard) supports a ATA PASS-THROUGH(32) SCSI command. It uses 7Fh as a operation code which means variable-length CDB. It would be great if kernel supports an ata pass-thru(32) command. Prior to development of ata pass-through in libata level, the definition of it should be added first.
