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. Signed-off-by: Jeff Layton <> Signed-off-by: Al Viro <>
