Are there locks in Linux where the waiting queue is FIFO? This seems like such an obvious thing, and yet I just discovered that pthread mutexes aren't FIFO, and semaphores apparently aren't FIFO either (I'm working on kernel 2.4 (homework))...

Does Linux have a lock with FIFO waiting queue, or is there an easy way to make one with existing mechanisms?
