Well, the reason people do is for hysterical... er, historical
reasons.  *Originaly* get_random_int() was introduced for use by the
networking folks, and some people think that get_random_int()
therefore "belongs" to the networking tree, even though there are
other users of get_random_int() and get_random_long() besides the
networking code.

I'd much rather break this obviously historical connection, but
patching people's wetware is a lot harder than getting a patch into
the kernel tree....
