Sorry, I still don't get it. If the flush_cache_page is doing something
necessary, then won't a user access in between it and invalidating pte
undo what was necessary? And if it's not necessary, why do we do it?
(For better performance would be a very good reason.)
If there are other writable mappings of the page, we can't swap
it out legally.
