One would have to check what are the current best practices for doing
that, i.e. probably this would have to go via
include/uapi//linux/tcp_states.h? Or take the time and create a new
header for the inet_diag.h stuff as this is not TCP specific for quite a
while?

If you could investigate how to properly expose this and then come back
with a patch proposal I think that would ease reviewing :-)
