[PATCH 12/31] selinux: tag avc cache alloc as non-critical

From: Suresh Jayaraman
Date: Thu Oct 01 2009 - 10:06:08 EST


From: Peter Zijlstra <a.p.zijlstra@xxxxxxxxx>

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