You need it internally otherwise you are screwed the moment you have 65536
volumes mounted - because you run out of unique device identifiers for stat.
Fortunately 32bit dev_t (not kdev_t .. which I think is what you are talking
about and will I assume go pointer to struct) is only one syscall change
