For all the UAPI changes, where are the defines "normally" found? i.e.
how does adding these to UAPI not break something that already has them?
Or have these never been defined before? I'm confused about how removing
the libc dependency exposes the lack of these defines. Are they defined
in a non-exported libc header somewhere?
