Subject: [RFC PATCH 0/9] Clean up and optimize sched averages
Date: Mon, 16 May 2016 02:59:25 +0800	[thread overview]
Message-ID: <1463338774-3324-1-git-send-email-yuyang.du@intel.com> (raw)

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: http://thread.gmane.org/gmane.linux.kernel/2214387/focus=2218488

Thanks,
Yuyang
