    I am concerned primarily about the lack of ability to get rid of such a
    handle in a controlled fashion. The udev/device unload case is simply one
    obvious way to exploit it.

    I still don't believe O_NODE makes sense without revoke(), and even then
    needs huge amounts of care on the device side of things.
