Yeah, I know, there's lots of interest in having a deadline scheduler.

One of the things we'll have to look at is removing all the EDF
assumptions from it.

I think we'll be wanting to do something like s/EDF/DEADLINE/
s/edf/deadline/ etc. on the code base to begin with.

I think the task model as exposed through sched_param_ex needs a little
more thought as well.

But anyway, I'm very glad to see the code.. and am hoping to have some
time myself to prod at the PI code to work with this.
