From 1efeb1c2415e7b5b5ce3ae0233d6c522f9e89d2d Mon Sep 17 00:00:00 2001

Subject: [PATCH 14/54] Smack: Ptrace access check mode
When the ptrace security hooks were split the addition of
a mode parameter was not taken advantage of in the Smack
ptrace access check. This changes the access check from
always looking for read and write access to using the
passed mode. This will make use of /proc much happier.
Targeted for git://git.gitorious.org/smack-next/kernel.git
