Might be worth fixing?
Also, I noticed this:

So in the #if 0 (inactive) section we change it from 10 to 20 ...

... then we change the actually active definition from 20 to 10?
Was that intended?
Please double check the 'make allyesconfig' disassembly of
kernel/sched/built-in.o
before/after this patch to make sure it does not change any code.
( No full allyesconfig build needed: 'make -j16 kernel/sched' should cut down on
the build time. )
Thanks,
