[Lxc-users] lxc-attach update?

Let me just explain my situation.
I'm trying to replace BSD Jails with Linux Containers and a vital part is
executing commands in a container from the outside (like jexec in FreeBSD)
The lxc-attach patch for 2.6.35.8 is working great. But there is a bug in
that kernel that prevents me from doing ANYTHING with IPv6.
The closest description of the bug I found is here
http://www.spinics.net/lists/netdev/msg149073.html
I can't even soft restart if I try to assign an IPv6 address or enable IPv6
forwarding because the kernel gets stuck at unregister_netdevice.
The bug seems to be fixed in 2.6.37-rc4.

So...I need to know when is the lxc-attach patch officially coming to the
kernel? In the foreseeable future? A week, month? In 2 years? 10? Or if
there is a patch for lxc-attach for let's say 2.6.38?
Which system calls are vital for the command so I can keep track of the
changes in the kernel? I see there is some work done in here
http://kernel.ubuntu.com/git?p=dlezcano/ubuntu-natty.git/.git;a=log
Does that mean it's working only in ubuntu 2.6.38.3 kernel or?

Thanks
