only broken case are:
(a) HW vendor driver specific resources (if they have crazy big list),
which cannot be abstracted out well enough, won't be controlled by
rdma cgroup.
(b) Such resource objects are not well defined today with new ABI model.
If such objects are well defined today, lets call them out and discuss
with Doug, Tejun, Christoph and larger group, whether they qualify for
inclusion or not.
rdma cgroup currently supports including handful of HW resource that
can be abstracted (at least at functionality level).
Please include any other option issue, if any.

From last discussion with Matan in this email thread, it appears that -
only broken case are:
(a) HW vendor driver specific resources (if they have crazy big list),
which cannot be abstracted out well enough, won't be controlled by
rdma cgroup.
(b) Such resource objects are not well defined today with new ABI model.
If such objects are well defined today, lets call them out and discuss
with Doug, Tejun, Christoph and larger group, whether they qualify for
inclusion or not.
rdma cgroup currently supports including handful of HW resource that
can be abstracted (at least at functionality level).
Please include any other option issue, if any.
