You can use bool instead, and that would give the same size saving while being even more descriptive. I think using bool could be safer, as the compiler would be able to detect some misuses and the values. But I could get even more saving by using bool with the field width: bool valid:1; bool valid_single_stream:1; That would place both variables into one byte. It may be ineffective for speed, but it's more effective for storage. In my configuration, I get following sizes: original (int): 2792138 your patch (u8): 2790186 bool: 2790186 bool (1 bit): 2789218 -- Regards, Pavel Roskin _______________________________________________ ath9k-devel mailing list [email protected] https://lists.ath9k.org/mailman/listinfo/ath9k-devel
