The Coda module was originally ported to NetBSD from Mach by rvb, and

then later to FreeBSD.  Update various NetBSD-related comments: in some
cases delete them because they don't appply, in others update to say
FreeBSD as they still apply but in FreeBSD (and might for that matter
no longer apply on NetBSD), and flag one case where I'm not sure
whether it applies.
