[Question] io cgroup subsystem threaded support

Posted to both cgroups and linux-block

Hi i read though some of the source code for cgroups, and from my understanding
the io cgroup subsystem does not support threaded cgroups. So i had some questions
regarding this.

 - Is there any future plans for supporting threaded?
 - What are the main hurdles in adding threaded support to the io cgroup subsystem?

Thanks,
Odin.
