I've acked the patch: my worry is only with the detail of your comments on the history - in my view it was always wrong to put on the active LRU there, and I'm glad that you have now fixed it. If you really want to test some workload on 2.6.28 to see if it too works better with your fix, I won't stop you - but I'd much prefer you to be applying your mind to 2.6.35 and 2.6.36!
