Ideally, if you agree with the generic approach, the next step would be to add your priority inheritance handling code to Linux semaphores and rw-semaphores. The sched.c bits for that looked pretty straightforward. The list walking is a bit ugly but probably unavoidable - the only other option would be 100 priority queues per semaphore -> yuck.
