> On lightly loaded systems, the result can be a 5-10% power savings. For callbacks that can't wait, there is a new call_rcu_hurry() function.

I was following this discussion at length, but didn't see the final patches. Is there a specific reason why `call_rcu_hurry` is not just `call_rcu_expedited`? Do we really need two *separate* flavors of "go faster", for a total of three variants?

I don't think call_rcu_expedited exists; a grep through the Linux source tree didn't find any examples. It seemed to have been proposed as an alternate name for call_rcu_hurry.
