Hi Gui,
I am not able to understand why do we need above changes?
BFQ scheduler already takes care of selecting an RT queue for dispatch (if
the queue is entitled to).
In case a new RT queue backlogged while a BE queue is being served, we
do preemtion check to make sure RT queue gets to run as soon as possible.
In fact I think that busy_rt_queues infrastructure is also redundant and
I plan to get rid of it.
Can you please help me understand what use case are you addressing with
above patch?
Thanks
Vivek
