I believe this is already in the -mm tree (from the sock memcg fixes) But actually, my main trouble with this series here, is that I am basing it on Pekka's tree, while some of the fixes are in -mm already. If I'd base it on -mm I would lose some of the stuff as well. Maybe Pekka can merge the current -mm with his tree? So far I am happy with getting comments from people about the code, so I did not get overly concerned about that. _______________________________________________ Devel mailing list [email protected] https://openvz.org/mailman/listinfo/devel
