Precedence: bulk

Version 4:

    * 'xdp_umem_clear_dev' exposed to be used while unregistering.
    * Added XDP socket state to track if resources already unbinded.
    * Splitted in two fixes.

Version 3:

    * Declaration lines ordered from longest to shortest.
    * Checking of event type moved to the top to avoid unnecessary
      locking.

Version 2:

    * Completely re-implemented using netdev event handler.

Ilya Maximets (2):
  xdp: hold device for umem regardless of zero-copy mode
  xdp: fix hang while unregistering device bound to xdp socket
