I have a more specific question.
Can we implement EXACTLY the same interface as Apple has -- so a
cross-platform application doesn't have to change? (I see an Apple
source license on that qos.h -- is that an issue with an API?)
(I think the answer about the scheduling interface is simply "yes", we
can add new Linux-specific flags to the existing sched_setattr(2) --
but ideally applications should be using a more portable interface,
rather than directly invoking linux-specific system calls)
thanks,
-Len
