From: jmerkey@...fmountaingroup.com
To: linux-kernel@...r.kernel.org
Subject: [PATCH 2.6.27-rc1-git5 4/26] mdb: changes to conform to Linux coding standards
Centralized external definitions into include files and corrected
the file to conform to Linux coding practices. fixed word wrap
problems with patches.
Moved kernel includes into main files, removed DATE and FILENAME
references from code.
