Comment (by joel.sherrill):

 The EDF scheduler should NOT use priority to store the deadline. That is
 one issue and it shows itself by bogus values being returned when you
 obtain the current priority. So #2 is **NOT** acceptable to me. The EDF
 scheduler should use its own internal stored value to sort the threads.

 Why can't the scheduler use uptime and not ticks since boot?

 The EDF scheduler is broken in assuming it can rewrite a thread priority
 with a deadline.
