Hm, the only thing nvme-cli should be copying from Linux is the headers
defining ioctls and their arguments. The specification defined structures
and commands should be OS agnostic in the tooling, so personally I think
it's less work to let them evolve independently.

That said, it's a nice goal to keep them in sync if someone wants to
put the effort into that.
