OK, it did pass rcutorture's various !SMP scenarios, so this seems
plausible.

I am sending my main pull request today, but will also put this patch
where 0day and -next can see it. If it does OK with that and with
additional review/testing for a few days, I will send a second pull
request with that patch some time next week.
