[lxc-devel] PATCH: lxc-ps: blkio instead of ns in /proc/*/cgroup

[Yamamoto - Joe's Web Hosting]

Hi

In Linux kernel 3.0.0, lxc-ps does not show any container names.

I think it's due to the following change:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6-stable.git;a=commit;h=1bdcd78e2445f1ef7097a3ae7ef12e8f9c4fb05f

`ns' no longer appears in /proc/*/cgroups.
Instead, blkio starts appearing now.

Here is a simple fix.

             $container = $_;


Thanks.
