There's a possibility: we will use the previous freq to update if
next_f is reduced for busy CPU if need_freq_update is set in
sugov_update_next_freq().  

Right.

This possibility would happen now? And this
update is what we want if it happens?  

This is exactly what we want here, don't reduce speed for busy CPU,

I understand it should not skip this update but set the same freq as
previous one again for the specail case if need_freq_update is set. Am
i rt?

but we also need to make sure we are in the policy's valid range
which cpufreq core will take care of.

I am not sure what's there to send now.
