That's a strawman argument - I was reacting to the combined effect of your series:

A subset of the patches might be fine and note that in fact I already picked a
patch from your series that made sense, I committed this patch of yours three days
ago:
f5832c1998af: sched/core: Omit building stop_sched_class when !SMP
I'll pick others as well as long as they don't complicate the code. Please send a
revised series that only does unambiguous complexity reduction/cleanups.
Thanks,
Ingo
