Subject: [PATCH 02/11] selinux: tag avc cache alloc as non-critical
Date: Mon, 6 Feb 2012 22:56:32 +0000 [thread overview]
Message-ID: <1328569001-17599-3-git-send-email-mgorman@suse.de> (raw)
In-Reply-To: <1328569001-17599-1-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.
