Subject: [PATCH 12/31] selinux: tag avc cache alloc as non-critical
Date: Thu, 1 Oct 2009 19:36:57 +0530 [thread overview]
Message-ID: <1254406017-16084-1-git-send-email-sjayaraman@suse.de> (raw)
From: Peter Zijlstra <a.p.zijlstra@chello.nl>
Failing to allocate a cache entry will only harm performance not correctness.
Do not consume valuable reserve pages for something like that.
