However, only memory release happens on the\n1 -> 0 transition; the unlink from hashes can occur with any refcount.\n\nUncooperative userspace can force a situation where a queue is pending\nfor destruction from netlink event while a different socket with same\nportid processes an UNBIND request.\n\nWith right timing, this will unhash the instance again:\n\nOops: general protection fault,
