Oh, but you weren't cc'd on that part of the thread, since the thread got started from Michal Hocko's similar trouble. So you may have never even noticed that patch, or my "improved LIST_DEBUG" patch in the same thread) You can find Eric Dumazet's patch on lkml (see the background at http://lkml.org/lkml/2011/2/17/267 and you'll see Dumazet's reply and my improved list debugging too). Eric Dumazet: have you made any other changes to that patch? Or should Eric (too many Eric's in this thread ;) just test the patch you posted?
