Yes, -stable maintainers have been asked to only backport patches where the MM developers asked for that, with cc:stable. There may be slipups, but as far as I know this is working. I don't actually know how they determine which patches need this special treatment. Pathname? Signed-off-by:akpm? > But we can always jump in and say that something should not go to stable > trees. Yes, please jump in if there are any thoughts about ordering/priority/timing. In fact, please jump in if there are any thoughts at all ;)
