I'm sure you're totally uninterested in this, but the above will probably generate warnings on (say) ppc64, where u64 is implemented as unsigned long.
I usually chuck a simple `-1' in there and the compiler always gets it right, regardless of signedness and size and architecture. - 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/
