It is wrong in the sense that without an architecture-specific synchronization at the end it is not guaranteed to work. It will work fine on x86 and presumably any other architecture where icache-dcache coherency is enforced in hardware (I am *guessing* that includes all or most SMP platforms, but it is definitely *not* true on all UP platforms.) -hpa -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
