These two are the main ones:

http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=408d85441cd5a9bd6bc851d677a10c605ed8db5f
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=4ff1ffb4870b007b86f21e5f27eeb11498c4c077

They shouldn't be too hard to backport.

I'd be interested to know how OOM and page reclaim behaves after these patches
(or with a newer kernel).

Thanks,
Nick
