From ed5215a21460f63d6bdc118cb55a9e6d1b433f35 Mon Sep 17 00:00:00 2001 From: Thomas Liu Date: Thu, 9 Jul 2009 10:00:29 -0400 Subject: [PATCH] Move variable function in lsm_audit.h into SMACK private space Moved variable function in include/linux/lsm_audit.h into the smack_audit_data struct since it is never used outside of it. Also removed setting of function in the COMMON_AUDIT_DATA_INIT macro because that variable is now private to SMACK.
