Yes. Embedded people(at least, me) want it. That's because they don't
have any swap device so they could reclaim only page cache page.
And many page cache pages are mapped at address space of
application(ex, android uses java model so many pages are mapped by
application's address space). It means it's hard to reclaim them
without lagging.
So I have a interest in this patch.
