Subject: [patch 3/5] Apply the PG_sensitive flag to audit subsystem
Date: Wed, 20 May 2009 11:50:05 -0700 [thread overview]
Message-ID: <20090520185005.GC10756@oblivion.subreption.com> (raw)
This patch deploys the use of the PG_sensitive page allocator flag
within the audit subsystem. It's not necessarily a high profile
target for use of this flag, but could be expected to contain
potentially sensitive information under some circumstances.
