Subject: [RFC][PATCH 8/9] ima: include tmpfs in ima_appraise_tcb policy
Date: Wed,  7 Jan 2015 15:52:59 -0500	[thread overview]
Message-ID: <1420663980-20842-9-git-send-email-zohar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1420663980-20842-1-git-send-email-zohar@linux.vnet.ibm.com>

Now that the rootfs includes extended attributes, don't
automatically exclude tmpfs file systems from being appraised.
