OSR Device Tree reference count

Hi,
Using OSR device tree you can see for each device its references.
How can I access to this parameter?
In which structure is it member?

OS.

For device objects, in the DeviceObject itself , but it aint safe to play with it whithout IO manager locks held. So forget it.
