When direct reclaim encounters a dirty page, it gets recycled around
the LRU for another cycle. This patch marks the page PageReclaim
similar to deactivate_page() so that the page gets reclaimed almost
immediately after the page gets cleaned. This is to avoid reclaiming
clean pages that are younger than a dirty page encountered at the
end of the LRU that might have been something like a use-once page.

I'm thinking we may need to add some code to
ClearPageReclaim to mark_page_accessed, but
that would be completely independent of these
patches, so ...
