From 88f304c9f43f25b0d0a5273bf9ff2a4a9ebd3988 Mon Sep 17 00:00:00 2001 From: Alexandre Montplaisir Date: Fri, 24 Sep 2010 17:12:53 -0400 Subject: [PATCH] Add module-unloading capabilities to ltt-disarmall Make ltt-disarmall unload all the kernel modules before exiting. The module list is not in the same order as in ltt-armall, because of some dependencies between the modules.
