I understand your concern, and agree that using the array as resource
manager is not the best way. But for now it's not possible as you know.
We need a better resource manager for PCI subsystem to manage the
various resources (traditional, device specific, bus related), which is
another independent work from SR-IOV change.

The array is obvious straightforward and can be easily replaced with a
more advanced resource manager in the future. So I don't think we going
further from or closer to the goal.
