You are correct - if there is a need for this, it would be better done in the kernel.
I'm just not sure how to explain both a "procs" and "tasks" interface file in a way that won't confuse people.
We have:
# echo {task-id} > tasks .... adds a single task to this resource group # cat tasks ... shows all the tasks in this resource group
and you want:
# echo {process-id} > procs ... adds all threads in {process-id} to this resource group # cat procs ... shows all processes (like "cat tasks" above, but only shows main thread in a multi-threads process)
