Close, but what I really want is to free up a specified amount of page
cache. So, if I want to remove 16M from a UML, and get_free_pages can
only give me 10 before returning NULL, then I want to say "drop 6M of
cache, and make it the oldest 6M".
Conceptually, I want to put memory pressure on the thing until it
drops enough cache to free the memory I want.
