So pinunpin-cas-original-fix is my version with a bug fixed, and
pinunpin-cas is what exactly? Your earlier version with the xadd +
cmpxchg?
The results look pretty good. Could you give a few more details about
the hardware and workload (i.e. cpu model number + scale)?
So the plan would be to finish cleaning this up into a committable
shape?
Greetings,
Andres Freund
