Hi Shirley,

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
