Hello LKML!

What am I doing terrible wrong that I do not get any comment on this
patch?

Subject: [PATCH] doc: Updated Documentation/nfsroot.txt
From: Arthur Othieno <apgo@patchbomb.org>

From: Nico Schottelius <nico-kernel@schottelius.org>

I today booted the first time my embedded device using Linux 2.6.15.2,
which was booted by pxelinux, which then bootet itself from the nfsroot.

This went pretty fine, but when I was reading through
Documentation/nfsroot.txt I saw that there are some more modern versions
available of loading the kernel and passing parameters.

So I added them and the patch for that is attached to this mail.
