Frankly, I'm tempted to take sparse RCU annotations out for good -
they are far too noisy and I'm not sure sparse is suitable for the
analysis needed to prove safety of that stuff, so unless you (or
somebody else) figures out how to use them in a reasonably clean
way, we'd probably be better off just dropping them.
