Hi Julien,

Thank you for your observations. You're absolutely right about this.

Currently, the sci_relinquish_resources call doesn't perform any operations
because the single-agent doesn't implement a callback.

I'll move the sci implementation to be positioned above the tee
implementation
and prepare a patch for this change.

Thanks! I think this change should go in Xen 4.21. Please tag it with [for-4.21] or similar. 

In one of previous replies we already agreed that it is fine to have this patch series in
4-21. Just to be sure:
 Release-Acked-by: Oleksii Kurochko <oleksii.kurochko@gmail.com>

Thanks.
