Re: [PATCH v14 09/13] sched/debug: Add migration stats due to non preferred CPUs

From: sashiko-bot@kernel.org

Add a new per-task stat,
- nr_migrations_cpu_non_preferred: number of push migrations while the
  CPU is non-preferred.

Since this new stat is per-task, it changes only /proc/<pid>/sched.
It doesn't update /proc/schedstat. Hence increasing the schedstat version
is not necessary.
