I guess he was thinking of using cmpxchg; but we don't support this in portable code. RCU is not really suitable for this because it assume writing is relatively rare which is definitely not the case for a qdisc. Also general list management with RCU is quite expensive anyways -- it would require a full copy (that is the 'C' in RCU which Linux generally doesn't use at all) -Andi - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
