In https://lore.kernel.org/linux-rt-users/CALOAHbDZPo65Vc89sVCuYkJ6vr=zD-4ev=JN=j7ZAzKHzRibdA@mail.gmail.com/#t,
Yafang Shao <laoar.shao@gmail.com> proposed changes to schedstats that
would add support for RT-relevant schedulers to schedstats.  As far as
I can tell, these patches were neither merged nor explicitly rejected.
  Is that correct?    If mainline kernel has not accepted them, is
there any reason that linux-rt-devel should not?    Perhaps
linux-rt-devel wants to stop accepting patches that are not part of
mainline in preference for moving them to staging in anticipation of
becoming a pure-Kconfig option?

The scheduler maintainer didn't give any feedback on this patchset.
Maybe they don't have any interest in it or they ignored it.

I think the best way is to merge this patchset to the mainline kernel first.

This feature can be disabled by setting  kernel.sched_schedstats to 0,
so I don't think we need to add a new option for RT schedstats.

I will refresh this patchset and resend it again.  Hope the maintainer
can give some feedback on it.
