What handles the reference counting for this object?  Shouldn't this be
a real 'struct device' and just have a pointer to the parent?  Otherwise
how do you know when to free this?


Reference counting is not needed on the gh_rm_rpc object because its only client (the VM manager) is torn down before the gh_rm_rpc.

Thanks,
Elliot
