This patch provides a vruntime based way to compare two cfs task's
priority, be it on the same cpu or different threads of the same core.
When the two tasks are on the same CPU, we just need to find a common
cfs_rq both sched_entities are on and then do the comparison.
When the two tasks are on
2 matches
