Surely you only need a single on of those.
Oh wow! I don't know how I missed this :) Thanks!

I don't think that actually works right on the current tree. In
particular look at commit:
31e77c93e432 ("sched/fair: Update blocked load when newly idle")
OK. I see from LKML the code has moved.
However, when I clone from
https://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git/
I cannot see the commit.
