I forgot to say. Some of the people that sent comments where:
  Marcin Slusarz <marcin.slusarz@gmail.com>
  Evgeniy Polyakov <zbr@ioremap.net>
  Jeff Garzik <jeff@garzik.org>
  Pavel Machek <pavel@suse.cz>
  Benny Halevy <bhalevy@panasas.com>
  Alan Cox <alan@lxorguk.ukuu.org.uk>
  Andrew Morton <akpm@linux-foundation.org>

And then there was a long flame war about user-mode API, which I now
have, and all in kernel utilities are gone.

To the best of my knowledge I have addressed all comments, at least
no one complained.
