Hello,

Sorry about tardiness.

Yes, maybe it'd be useful to come up with a terminology for them. e.g.
terminal - once a task reaches a terminal DSQ, the only way that the BPF
scheduler can affect the task is by triggering re-enqueue (although we don't
yet support reenqueueing global DSQs).

Thanks.
