Good eyes, thank you!
I applied and pushed all three with modified commit logs. Please check
to make sure that I didn't mess anything up. If testing and reviews
are OK, I expect to submit them for the v5.2 merge window.
I had to hand-apply this one, so in future patches could you please
generate them against -rcu? It may be found here:
git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git
Thanx, Paul

Thanks Paul, I reviewed the patches on -rcu; they look good. Thanks for
applying them! I will move my codebase to -rcu, for all future work.
Thanks
