Message-ID: <20070730170911.GA7687@c2.user-mode-linux.org>
Date: Mon, 30 Jul 2007 13:09:11 -0400
From: Jeff Dike <jdike@...toit.com>
To: Andrew Morton <akpm@...l.org>
Cc: LKML <linux-kernel@...r.kernel.org>,
uml-devel <user-mode-linux-devel@...ts.sourceforge.net>
Subject: [PATCH 1/4] UML - Move userspace code to userspace file
Move some code from a kernelspace file to a userspace file where it
fits better. This enables some tidying which is the subject of a
later patch.
