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().
