Subject: [RFC PATCH 0/9] Clean up and optimize sched averages

Hi Peter,

Continue the left patches in this series. I realized some patches should
need thorough discussion (finally), so this post is marked RFC.

 - For LOAD_AVG_MAX_N, I am OK to stick to the old value, but it is worthwhile
   to get it cleared to the true value.

 - About the renames, I noticed there is an existing sched_avg_update(), but
   anyway, please NAK the renames you don't want, hopefully not all, ;)

 - Removing scale_load_down() for load_avg may have some unknown ramifications,
   is it worth trying?

The previous post is at:
