Sounds good. But I would suggest this to go to -stable as soon as possible. Because this bug is affecting the basic functionality of DCCP. It crashes kernel whenever a new socket in this module is created.

Best,

    Great; thank you! Sorry I dropped the ball on this series. I got
    distracted. :) It looks like akpm took it into -mm now, so this should
    be fixed in -next soon.
