Subject: [PATCH -v4 00/10] sched/balancing: Misc updates & cleanups

Improve a handful of things I noticed while looking through the
scheduler balancing code. No change in functionality intended.

Changes in -v4:

 - Incorporate review feedback
 - Bump SCHEDSTAT_VERSION to 16, due to the changed order of colums
 - Allow CONFIG_SCHEDSTAT builds more widely

Thanks,

     Ingo
