Yeah.  I suspect that's why Bill named it that in the first place.

What about zeroed_page_cache?

Now, this opens up another can of worms in terms of where to
initialize that cache in the first place.  pgtable_cache_init() might
not be the best place if it's generally used.  Only requirement is
that it needs to be early.
