Because if you give guarantees on something, ppl start using such guarantee in the wrong way. Kyle's email summarizes it. This should really be treated as an opaque handle, with no assumption on its value. And if you start handing over values that are not predictable, the userspace is *forced* to not use any assumption on its values. I never made any assumption on values returned by APIs returning "handles", and I never had any problem (or even care) about how those values were distributed in the N bit space. - Davide - 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/
