The runstate is actually updated just not for the guest. It will be done
at the next context switch. But I am not convinced you will actually see
a major differences in number here. Do you have figures?
Lastly, as you can see, I don't have the same opinions as you for the
issues. It may have helped if you provided a descriptive cover letter
explaining the issues rather than assuming we are all on the same page.
Cheers,
