Look at it from the semantical POV first, which is the most important one. semaphores are semantically different from mutexes, so they require different APIs. When you have semantically different APIs, you can still implement them for whatever (e.g. peformance) reason on top of the same mechanism, but you can not make this work the other way round. tglx - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
