Hi Johannes,
Thanks for your time on reviewing this. I will make changes following
your review. See details below.
By the way, I'm still struggling on how to run unit tests. It might
take time for me to make it run on my machine.

inet6_ifa_finish_destroy() already uses kfree_rcu() to free
inet6_ifaddr structs.
We need to use proper list additions/deletions in order
to allow readers to use RCU instead of idev->lock rwlock.

By extending the rcu section a bit, we can avoid these

Callers hold rcu_read_lock(), so we do not need
the rcu_read_lock()/rcu_read_unlock() pair.

Sending IPv6 udp packets on non connected sockets is quite slow,
because ipv6_dev_get_saddr() is still using an rwlock and silly
references games on ifa.

When a bundling message is received, the function tipc_link_input()
calls function tipc_msg_extract() to unbundle all inner messages of
the bundling message before adding them to input queue.
The function tipc_msg_extract() just clones all inner skb for all
inner messagges from the bundling skb. T

We change the initialization of the skb transmit buffer queues
in the functions tipc_bcast_xmit() and tipc_rcast_xmit() to also
initialize their spinlocks. This is needed because we may, during
error conditions, need to call skb_queue_purge() on those queues
further down the stack.

The parameter extack was added to batadv_softif_slave_add without adding
