[PATCH 0/2] ima: don't measure/appraise files on configfs

When IMA appraises/measures a file configfs, it has an opportunity to
hold onto the ima_iint_mutex while another file from a different file
system is attempting to appraise/measure. This may cause a cyclical
lock dependency.

Add configfs to the default don't measure/appraise lists, similarly to
other pseudo file systems.
