Ok, here is a compromise proposal. I don't care very much about the MKDEV macro and almost nobody else should care about it either. My main concern with a larger dev_t is that people start to go wild and waste the number range with crap. So what I'd like to see is some usage policy, e.g. nobody should assume a certain dev_t size, so that it's still possible to scale it down. If the user has only a small number of devices, they should be addressable even with a 16 bit dev_t.
BTW there are a few more functions missing, we need a dev_to_u32() and a dev_to_u16(), so e.g. file systems can do something useful in mknod if they can't store the complete number.
bye, Roman
