Subject: [PATCH v3 0/5] sched/fair: Fix attach and detach sched avgs for task group change or sched class change
Date: Wed,  1 Jun 2016 11:41:01 +0800	[thread overview]
Message-ID: <1464752466-3494-1-git-send-email-yuyang.du@intel.com> (raw)

Hi Peter,

It seems the problem is even worse, and this fix hopefully should have
fixed Vincent's addressed issue too.

Thanks,
Yuyang
