I'd agree with you, except that systm.h also includes a struct
definition, which is (potentially) useful to kmem readers, kernel
coredump grovelers, LKMs that want to use that data structure, etc.

At least $NetBSD: systm.h,v 1996/06/11 13:18:43 briggs Exp $
does.... :-)

(Tangent: is _KERNEL supposed to be defined for LKMs?  Or am I just
showing I haven't read some manpage?)
