Both look correct to me, and I think this allows us to make more
optimizations in percpu-rwsem.c.
I am not sure about the naming... Yes, it relies on rcu but this is
just implementation detail. But this is cosmetic and I can't suggest
something better than rcuwait.
Well, speaking of naming, rcuwait_trywake() doesn't look good to me,
rcuwait_wake_up() looks better, "try" is misleading imo. But this is
cosmetic/subjective too.
