Where I see negative impact of the __dequeue_task() update is when
probe components compete in one cgroup, ie pinned wakelat and 8 pinned
hogs used to measure the delta between smp and concur CPU distribution
modes during cgroup vs cgroup testing, all stuffed into one cgroup.

Do whatever you like there, just keep update_curr() far away from
cfs_rq_of(se) and probe goes silent. For virgin flat in isolation,
that was the only signal the probe generated.
