Subject: [PATCH 2.6.27-rc1-git5 23/26] mdb: add kallsyms fixes for duplicate names
Sender: linux-kernel-owner@vger.kernel.org
Content-Length: 1926
Lines: 66

Centralized external definitions into include files and corrected 
the file to conform to Linux coding practices.  fixed word wrap
problems with patches.

add the ability to call through kallsyms and output strstr() matches
for name searches, since modules can have functions that share identical
names with the kernel functions.
