Re: [RFC,v2 3/3] sched: ignore task_h_load for CPU_NEWLY_IDLE

Hello. Let's decide how to proceed with https://lkml.org/lkml/2017/2/14/334 patch. Despite it is not a big change, i think it is important and ready to be submited, unless there are still any comments. -- Uladzislau Rezki On Thu, Feb 16, 2017 at 12:20 PM, Uladzislau Rezki
