Yea. I'm not really psyched about overloading the vread pointer's use. I mentioned it could be done if the #ifdef was objected to, but it seems a bit abusive. The #ifdef isn't great, but I think its something I can live with for now. At least its explicit. > It would need to change in the future if vread was needed. > I have no strong argument against using it. Yea. I'd hold off on that for now. thanks -john - 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/
