Subject: [RFC PATCH v4 3/5] ima: differentiate auditing policy rules from "audit" actions

From: Mimi Zohar <zohar@...ux.vnet.ibm.com>

The AUDIT_INTEGRITY_RULE is used for auditing IMA policy rules and
the IMA "audit" policy action.  This patch defines AUDIT_INTEGRITY_POLICY
to reflect the IMA policy rules.
