Thank you! I have pulled this into -rcu as branch ctxt.2022.06.29a. If testing goes well, I will re-merge it into branch "dev".
The diffs from the earlier version are indeed small, as promised.
I did reword the authorship of 06/20 and 09/20 because this looked to me to be feedback rather than authorship. I credited Max like this:
[ frederic: Apply Max Filippov feedback. ]
If you feel strongly about Max having authorship, please set this up using the Co-developed-by rules shown in submitting-patches.rst and send me an update.
Thanx, Paul
