Both netdev_lock() and netdev_lock_ops() are called before list_netdevice() in register_netdevice(). No other context can access the struct net_device, so we don't need these locks in this context.That's technically true, but it will set off a bunch of lockdep warnings :-(
Let me drop it for now from the nipa because it does complain about it: https://netdev-3.bots.linux.dev/vmksft-net-dbg/results/24641/67-nl-netdev-py/stderr --- pw-bot: cr
