From e3d6b07b8ba161f638b026feba0c3c97875d7f1c Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Wed, 10 Oct 2012 15:25:25 -0400 Subject: audit: optimize audit_compare_dname_path In the cases where we already know the length of the parent, pass it as a parm so we don't need to recompute it. In the cases where we don't know the length, pass in AUDIT_NAME_FULL (-1) to indicate that it should be determined.
