From 9cec9d68ae53aae60b4a1fca4505c75a1d026392 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Wed, 10 Oct 2012 15:25:21 -0400 Subject: [PATCH] audit: no need to walk list in audit_inode if name is NULL If name is NULL then the condition in the loop will never be true. Also, with this change, we can eliminate the check for n->name == NULL since the equivalence check will never be true if it is.
