I'd argue that the unistd_nr_*.h headers should not be in the uapi directory
but instead be included only from the in-kernel header.

It looks like you change and rename this file at the same time.
Generally speaking, I would not do that in one patch. Either
leave the slightly inconsistent name unchanged, or rename
it in a separate patch.
