Subject: Support for global block IO throttling?

Hi,

Are there any plans to support global (per cgroup) IO throttling in
the near future? I'm in need of this and would gladly work on it if
nobody else is and if people think this is a useful feature. What I
envision is that one can specify the limits of individual devices in a
group but also specify the overall aggregate limit of the whole group.
I just started looking at the throttling code and haven't quite
figured it out yet so it might take me a bit to get up to speed.

Thanks
...Juerg
