Randy, While on the subject of traditions, how about the C90 and C99 ones? C identifiers starting with "__" are reserved! Reference: ISO/IEC 9899:1999 (C99) section 7.1.3 "All identifiers that start with an underscore and either an upper case letter or another underscore are always reserved for any use". It was the same in C90. Now we might start getting rid of __u32 and its friends first :-) Doug Gilbert - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
