Why not just have a single array and have nfsd4_decode_clientid itself check the minor version? That'd work too. Every operation that's been introduced more recently than 4.0 or that's since been deprecated would need a version check at the top of its decoder. That'd be a dozen or so. But the information has to go somewhere and perhaps that's more straightforward than sticking this in data.... OK, I'd be fine with that. --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
