This is a fusyn-specific optimization. INT_MAX is set to be the lowest prio and the one used by non-PI waiters, so it will never interfere with normal priorities. Because this is probably going to be most of the cases and we know it will always be the last one, it is a shortcut for it. It makes some sense, but in a more generic scenario, I might not. -- Inaky - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
