> We need to get rid of the artifical major/minor split completly
I do not disagree with you, but your point of view seems to be that either we make everything perfect or we do nothing. I prefer slow progress.
Concerning this split - traces of it occur in a very large number of places. Let me just mention the raw device that I did this afternoon. How does one connect a raw device with a block device? Using a struct raw_config_request from user space. And look
struct raw_config_request { int raw_minor; __u64 block_major; __u64 block_minor; };
One of the many places that has a built-in major/minor split. Basically this split is unimportant. A dev_t is just a cookie. But as soon as you start looking at details this split is all over the place.
