Actually, up and down don't imply mutex at all. So maybe it would be better to keep up and down as normal semaphores, rename what you want to mutex_lock / mutex_unlock which makes it obvious what it is, and then you can go through and find all the semaphores that are being used as mutexes (or is that mutices?) and make the change more incrementally.
