gcc will output
increment low 32bit if zero increment high
Which means we can rapidly get 2^32 out of sync
True and this equals the "fix" suggested C code involving two 32-bit counters that the original author posted :-)
So this makes both cases equally wrong. - 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/
