It uses charge API to perform resource charing before allocating low
level resource. It continues to link the resource to the owning
thread group leader task.
It uncharges the resource after successful deallocation of resource.

I will post the patch soon once I am done validating it.
Let me know if there are any design comments.

Hi,
I finally got some chance and progress on redesigning rdma cgroup
controller for the most use cases that we discussed in this email
chain.
I am posting RFC and soon code in new email.
