Thanks!
I'm adding
"Note that the CPU affinity of previously created threads will not get
adjusted."
and
"In general, the interface behaves like pthread_setaffinity_np(): host CPU
numbers that are currently not available are ignored; only host CPU
numbers that are impossible with the current kernel will fail. If the list of
host CPU numbers does not include a single CPU that is
available, setting the CPU affinity will fail."
This is one of the reasons why reviewing your work is such a pleasure:
not only do you answer my questions with clarity and patience, you
proactively improve your patches before I can even think to ask.
Thank you!
