-mm has a patch called vmscan-give-referenced-active-and-unmapped-pages-a-second-trip-around-the-lru.patch which has been sitting there for some time waiting for us to work out whether or not it is a desirable thing.
This patchset of yours apparently retains the change which vmscan-give-referenced-active-and-unmapped-pages-a-second-trip-around-the-lru.patch makes.
But do we know that it was a good one?
