Thats the only way to keep them consistent.
Likewise we do not have seperate copies of the core headers for
individual subsystems.

If one have to edit in two places when adding a list of constants for
example you can be sure at one point in time the second place is
What does this separation where user space headers live a life outside
the kernel buy us? As kernel developers we are free to think on the user
psace side - thats nice sometimes. But hiding in a hole is not the
way we create the best interfaces. That has the kernel model shwed many
times. It requires publicity and frequent usage to be good. Two thinks
that is harder to get when we hide.

But seen form the userspace perspective this is horrible.
They have to maintain a set of almost duplicated headers with
various licenses, sync problems etc. for absolutely no gain.
