Hmm, 1G+3G split? Will we have HIGHMEM option someday? ;-) How confident are you that you will never need more than two classes later and you will never need to split the larger space again? If you are not, and if the topic is to introduce incompatible output, would it be wiser to be even more forward looking and introduce different classes of marks with a backward incompatible syntax, perhaps like using ":\d+" for anything, and using ":[a-zA-Z0-9]+:\d+" for some application specific "class" of objects that is specifed by the [a-zA-Z0-9]+ part? -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
