----------------------------------

bq. If it's okay with you, I would like to keep number 1. If I remove number 2, 
but keep number 1, the behavior would be that the disable_preemption settings 
could be done in the parent, but they would only affect the leaf queues.
Make sense to me, looking forward for your updates!
