Re: [PATCH] sched: fix env->src_cpu for active migration

Regarding your sched_domain config and especially the flags field, you
should not be impacted by my patch because
- need_active_balance is the only new place that use env->src_cpu in
the load_balance function
- and your machine will never test the condition: "env->src_cpu >
env->dst_cpu" in need_active_balance because SD_ASYM_PACKING is not
set in your config

Have you tested the patch with others that could have modified the
load_balance function ?
