After a while, here's v2 of the series, also discussed at LSF/MM [1].
I've updated the documentation bits and expanded changelog. Also measured
effect on SLOB, and found it to be within noise. That required first adding
some accounting for SLOB, which I believe is useful in general, so that
became Patch 1. All other details are in Patch 2 changelog.
