Re: [PATCH v8 0/4] sched: Rewrite runnable load and utilization average tracking

[Yuyang Du <yuyang.du@intel.com>]

Hi Boqun,

Thanks for the tests.

Indeed I can't find the 8th versio myself in the archive. That is weird.
Vincent sure received the patches, but maybe not the list, then that is
interesting...

Anyway, I will rebase the patches up-to-date, and resend it to the list
shortly.

Regarding test results, "less than 50% sometimes" meaning imbalanced?
What about versus the stock kernel?

Regards,
Yuyang
