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
xdp: fix hang while unregistering device bound to xdp socket
