We're really close to eliminating page_size(). Just 23 callers left.
As such, it would be a mistake to name the header after it. I don't
particularly like how you're splitting up mm.h; I think the real problem
is all the code that says "Oh, I'm allocating memory, I should include
mm.h" instead of including gfp.h or slab.h.

But if you must split it like this, at least call it folio_size.h
