From 50c205f5e5c2e2af002fd4ef537ded79b90b1b56 Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Wed, 4 Apr 2012 15:01:43 -0400 Subject: LSM: do not initialize common_audit_data to 0 It isn't needed. If you don't set the type of the data associated with that type it is a pretty obvious programming bug. So why waste the cycles?
