Florian Westphal 377cb24884 rtnetlink: use rcu_dereference_raw to silence rcu splat ... Ido reports a rcu splat in __rtnl_register. The splat is correct; as rtnl_register doesn't grab any logs and doesn't use rcu locks either. It has always been like this. handler families are not registered in parallel so there are no races wrt. the kmalloc ordering. The only reason to use rcu_dereference in the first place was to avoid sparse from complaining about this. Thus this switches to _raw() to not have rcu checks here. The alternative is to add rtnl locking to register/unregister, however, I don't see a compelling reason to do so as this has been lockless for the past twenty years or so.
