no that commit doesn't help, because the issue isn't one of dst refcount leaks or delayed dst gc, the problem is kernel sockets that haven't closed yet holding a reference to the netns lo interface device via their dsts.

I do think I have a possible fix for this though, and I have some test kernels building in this ppa (please note they are currently building and will take a few more hours to finish):

can anyone please test with any of those kernels (they all contain the patch to maybe fix this)? In my testing it eliminated the problem completely, but I'd like to get some more diverse real-world testing before starting an upstream discussion on the patch.
