Subject: [PATCH net-next 0/9] net: hold instance lock during NETDEV_UP/REGISTER/UNREGISTER

Solving the issue reported by Cosmin in [0] requires consistent
lock during NETDEV_UP/REGISTER/UNREGISTER notifiers. This series
addresses that (along with some other fixes in net/ipv4/devinet.c
and net/ipv6/addrconf.c) and appends the patches from Jakub
that were conditional on locked NETDEV_UNREGISTER.
