Merge branch 'net-more-factorization-in-cleanup_net-paths'
Eric Dumazet says: ==================== net: more factorization in cleanup_net() paths This series is inspired by recent syzbot reports hinting to RTNL and workqueue abuses. rtnl_lock() is unfair to (single threaded) cleanup_net(), because many threads can cause contention on it. This series adds a new (struct pernet_operations) method, so that cleanup_net() can hold RTNL longer once it finally acquires it. It also factorizes unregister_netdevice_many(), to further reduce stalls in cleanup_net().
