Hi Shirley,

> Do you know if the PF_NO_SETAFFINITY flag can help in any way?

AFAIK, this will not work for kernel thread.

For example, with 4.8.13-1 kernel:
Display all kernel threads with
ps aux | grep "\["n

(as kernel threads are enclosed in square brackets, [ ])
And pick one of them and try:
taskset -pc 7 521
pid 521's current affinity list: 0-15
taskset: failed to set pid 521's affinity: Invalid argument
Regards,
Rami Rosen
