It appears "taskset" only works on regular programs, not kernel threads:
# taskset -p -c 1 2128
pid 2128's current affinity list: 0
taskset: failed to set pid 2128's affinity: Invalid argument
# taskset -p -c 1 2129
pid 2129's current affinity list: 1
taskset: failed to set pid 2129's affinity: Invalid argument
As the above shows, WG threads are already bound to a particular CPU and this
can't be changed.
