[ Upstream commit64d7d5abe2] rcu_derefence_raw() should not have been used here, it concealed this bug. Its used because struct rb_node lacks __rcu annotated pointers, so plain rcu_derefence causes sparse warnings. The major tradeoff is that rcu_derefence_raw() doesn't warn when the caller isn't in a rcu read section. Extend the rcu read lock scope accordingly and cause sparse warnings, those warnings are the lesser evil.
