Won't that generate a warning about assigning a signed quantity
to an unsigned variable?

What's really needed is a set of definitions along the lines of

#define MAX_U32 ((__u32) 0xFFFFFFFFUL)
#define MAX_U64 ((__u64) 0xFFFFFFFFFFFFFFFFULL)

but as an intermediate measure, how about...

__u64 uid = ((__u64) 0xFFFFFFFFFFFFFFFFULL);

Best wishes from Riley.
