Just a prod: I've not seen your fix go into the 2.6.29-rc tree yet. I confess that not even once since then have I seen the page allocation failure which led to the BUG you've fixed: though most of my testing has been on 2.6.29-rc kernels, so my guess would be that something else has changed to make a failure there less likely. But I do still carry your patch, and would be reassured to see it in. Thanks, Hugh
