[PATCH 02/12] selinux: tag avc cache alloc as non-critical

From: Mel Gorman <mgorman@suse.de>
Date: 2012-06-29 13:37:37
Also in: linux-mm, linux-nfs, lkml
Subsystem: selinux security module, the rest · Maintainers: Paul Moore, Stephen Smalley, Linus Torvalds

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