hi florian, i am on the side of error, the code increase is marginal and the speed penalty also, so why not ? you make sure that an overflow may never happen, and the rest in name gets zeroed. The problem is that when the error occurs it may be later than the actual changeset. NTL it is an hint, and if you feel ok with it and the maintainer has no objects i have no problems either. re, wh - 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
