Hello, Just sending a few patches before lazy rcu v6 can come out. That can come out after more testing to check feasibility of ideas discussed at LPC. I will try to get rcutop pushed as well before v6, but in the meanwhile I don't see much reason to block these few patches for 6.1. These apply to Paul's rcu/next branch. What do you think?
