Subject: linux-next: build failure after merge of the moduleh tree

Hi Paul,

After merging the moduleh tree, today's linux-next build (x86_64
allmodconfig) failed like this:

Caused by commit 0b068238c5ef ("The dm-bufio interface allows you to do
cached I/O on devices") interacting with the modul.h split up.  This file
should have included module.h in any case.

I have added this merg fix patch (Alasdair, this could be added to the
device-mapper tree):

Subject: [PATCH] device-mapper: dm-bufio.c needs to include module.h

since it uses the module facilities.
