This isn't going to work. You've effectively changed the types of the fields
in the UUID struct from BE to CPU-endian, but you're still calling
generate_random_uuid(), which produces a BE UUID. You need to leave the
struct members as __beXX or stop using the core UUID routines.

Just move the struct uuid_v1 as-is to the afs headers and rename it to struct
afs_uuid. You can then leave the (un)marshalling code alone.
