[PATCH 1/2] ima: "remove enforce checking duplication" merge fix

From: Mimi Zohar
Date: Sun Feb 24 2013 - 10:26:34 EST


Commit "750943a ima: remove enforce checking duplication" combined
the 'in IMA policy' and 'enforcing file integrity' checks. For
the non-file, kernel module verification, a specific check for
'enforcing file integrity' was not added. This patch adds the
check.
