Thanks Yuyang. AFAICS it should work, though I believe the test on
last_update_time could instead go at the top of migrate_task_rq_fair()?
It'd save the fn call to remove_entity_load_avg() and two unnecessary
assignments (as p->se.avg.last_update_time and p->se.exec_start = 0 for
newly forked tasks). This worked for me.

thanks,
Steve
