That bit isn't quite true - we don't use __GFP_ZERO in pte_alloc_one() &
instead call clear_highpage() on the allocated page. Not that I have a
problem with using __GFP_ZERO - it seems like the more optimal choice.
It just might be worth mentioning the change & expected equivalent
behavior.
Otherwise:
