I should have been clearer - this patch is to be applied on top of the
shrinker series (which is still under review). I originally included a comment
in the patch log, but it must have been accidentally dropped when I reworked
the patch according to Chris' and Johannes' suggestions.

Nevertheless, I have rebased it on top of current mm-unstable
(with the shrinker series on top), then sent out as v5 (with the second
suggestion from Chris Li) just in case.

Let me know if there are still issues! My apologies for the inconvenience
and lack of clarity.
