    Not really, but it's certainly a nice capability. However, iso9660
    (RockRidge, actually) has 64 bits of dev_t space; it's actually split
    into two 32-bit entries specified as "high 32 bits" and "low 32 bits."

    I'm not positive if Linux expects those to contain major:minor or
    0:<16-bit-dev_t>.
