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:

Thanx, Paul
