Subject: [Patch net-next] net: always pass struct netdev_notifier_info to netdevice notifiers
From: Cong Wang <amwang@...hat.com>
commit 351638e7deeed2ec8ce451b53d3 (net: pass info struct via netdevice notifier)
breaks booting of my KVM guest, this is due to we still forget to pass
struct netdev_notifier_info in several places. This patch completes it.
