From 4fdef2183e6598cc977a9bb9321ef99a44125da3 Mon Sep 17 00:00:00 2001 From: John Johansen Date: Sat, 5 Mar 2011 02:18:02 -0800 Subject: AppArmor: Cleanup make file to remove cruft and make it easier to read Cleanups based on comments from Sam Ravnborg, * remove references to the currently unused af_names.h * add rlim_names.h to clean-files: * rework cmd_make-XXX to make them more readable by adding comments, reworking the expressions to put logical components on individual lines, and keep lines < 80 characters.
