Yes, but this should be layered on top of the page handling ---
there's no need to integrate it into the low levels of the page cache.

Same as above.  When the pagebuf layer or whatever gets a write
request for a given page, it is perfectly at liberty to write out
adjacent pages too if it wants to.  The VM doesn't have to enforce
that itself.
