Thank you for the detailed feedback and for taking the time to review
this patch.

Your approach is indeed much simpler and more elegant. I see no issues
with it, and it has the additional benefit of improving the evaluation
regardless of context, rather than being restricted to nohz_full CPUs
and the idle task. This is clearly a better solution.

I appreciate the learning opportunity - working on kernel development
continues to teach me new and interesting things every day.

Should I prepare a v2 based on your suggestion, or would you prefer to
submit this as a separate patch?

Thanks again,
Ionut
