My 2 cents: I liked the idea... But, I agree with peterz. This cannot fundamentally deal with deadline scheduler. In the deadline scheduler, the priority is set at every new sporadic activation of the task (it is a fixed job priority scheduler - not a fixed priority scheduler). The priority is the deadline of the new job. The deadline is an u64, that does not fit in the int prio - so it cannot be reused. -- Daniel
