Great work, Gary! I very much like how the implementation turns out overall
(will go over the details in the next days).
FYI, once ready I will merge this with a "Merge patch series" merge commit to
retain the cover letter as I did with the driver lifetime series previously.

(Either on the relevant patches or just the cover letter, both is fine with me.)
