It looks like your using sched_clock() through out .. It's a little troubling considering the constraints on the function .. Most architecture implement a jiffies sched_clock() w/ 1 millisecond or worse resolution.. I'd imagine a millisecond hold time is pretty rare, even a millisecond wait time might be fairly rare too .. There's also no guarantee that sched_clock timestamps off two different cpu's can be compared (or at least that's my understanding) ..
