I expect you'll find that it isn't that easy. There are a lot of opaque copies that copy whole structures. You'll need a whole compat layer, similar to 32<->64bit compat layers, but actually doing more work because it has to handle all fields larger than one byte, not just fields which differ in size. -Andi
