Mmmm, if you have a broken out patch, it'd be preferable. If I were to apply the whole of -mjb, I'll get a damned sight better results than any of them, but that's not really a fair comparison ;-) I'll can at least check it's stable for me that way though. I did find your broken-out anon-vma patch, but it's against something else, maybe half-way up your tree or something, and I didn't bother trying to fix it ;-) M.
