Subject: [PATCH bpf v5 0/2] xdp: fix hang while unregistering device bound to xdp socket

Version 5:

* Fixed incorrect handling of rtnl_lock.

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
