[question] Is there a plan to introduce a unified co-scheduling mechanism to CFS ?

Hi,

Is it worthy to introduce a unified co-scheduling mechanism to CFS ?
Because multiple cooperating threads or tasks frequently synchronize 
with each other,
not executing them concurrently would only increase the latency of 
synchronization.
For example, a thread blocking in spinlock to waiting for another thread 
to release the same spinlock
might reduce its waiting time by being executed concurrently with the 
thread which hold the same spinlock.
In virtualization scenario, multiple vcpus (which belong to the same vm) 
co-scheduling is more desired
when several cooperating threads/task is running in guest.

Is there a plane for this work?

Thanks,
