Right, I saw Eric's patches were pulled by Linus during this merge
window. IIRC, it's from here:
http://git.kernel.org/?p=linux/kernel/git/ebiederm/user-namespace.git;a=shortlog
Totally 46 patches.

Where is these remaining setns patches?

Nice, do you know where are these patches hosted? any git tree for pulling?

Exactly, these pid namespace patches look like quite old now. Probably
we should wait for Eric's new set.

If there is no git, please forward. Thanks.

Serge, my plan to setup lxc as test environment for our further
kernel, which should include Eric's or others' user namespace patches.
I tried your lxctest on my OMAP4 Panda board. I think some testing
failed, please find my log here: http://pastebin.ubuntu.com/1006351/

I really appreciate you can help to take a look at this.

Thanks a lot,
