[RFC PATCHSET v2] sched/fair: fix load balancer behavior when cgroup is in use

Show all headers | View raw

Hello,

v1 posting can be found at

  http://lkml.kernel.org/r/20170424201344.GA14169@wtj.duckdns.org

The patchset is still RFC and based on v4.11.  I used Peter's updated
calc_cfs_shares() instead of scaling manually and updated so that
runnable_load_avg is propagated independently from load_avg.  Due to
the way sched_entity and cfs_rq loads are calculated, this requires an
extra runnable_load_avg calculation for group sched_entities, but the
end result is cleaner and actually makes sense.

Vincent, can you please verify whether the regression that you see is
gone with this version?

Thanks.
