Please queue some netns bug fixes for stable

Hi, David


Please queue the following commits for -stable, all kernels < 3.12.

You backported the last one (from me) to 3.14 and 3.12, but for kernels < 3.12
we probably need all of these three:

    rtnetlink: wait for unregistering devices in rtnl_link_unregister()


AFAIK, all 3.x kernels are affected. Eric should know better than me here.

Thanks!
