Subject: [PATCH 02/12] selinux: tag avc cache alloc as non-critical
Date: Thu, 12 Jul 2012 07:40:56 +0100 [thread overview]
Message-ID: <1342075266-29593-3-git-send-email-mgorman@suse.de> (raw)
In-Reply-To: <1342075266-29593-1-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.
