Subject: [PATCH 02/12] selinux: tag avc cache alloc as non-critical
Date: Fri, 29 Jun 2012 14:33:15 +0100	[thread overview]
Message-ID: <1340976805-5799-3-git-send-email-mgorman@suse.de> (raw)
In-Reply-To: <1340976805-5799-1-git-send-email-mgorman@suse.de>

Failing to allocate a cache entry will only harm performance not
correctness.  Do not consume valuable reserve pages for something
like that.
