I guess it would improve system performance very well.
But as I wrote down in description, downside of the patch is that we have to
age anon lru although we don't have swap. But gain via the patch is bigger than
loss via aging of anon lru when memory pressure happens. I don't see other downside
other than it. What do you think about it?
(I didn't implement anon lru aging in case of no-swap but it's trivial
once we decide)

I am a bit confused like some of the others as to why this patch is
necessary since we already have DONT_NEED.
