Okay, can you suggest a better one? That's the best I could come up with that wasn't long winded.


How about apply_to_page_range()?


That would be better.


secondly, I think you confuse our (confusing) terminology: the page
that holds pte_ts is not the pte_page, the pte_page is the page that
a pte points to


What should we call it? Essentially we want to be able to get the physical address of a PTE in some cases, and passing struct page pointer seemed the best way to be able to derive that. I can rename it to something else vaguely plausible if the only problem is the semantic clash with Linux's idiomatic use of pte_page.


Looks like pmd_page is correct?


Yes... although maybe you could just pass the 'pmd_t *'? That's
what a lot of the mm/memory.c code does.
