Subject: [PATCH 3/8] sched, numa, mm: Add credits for NUMA placement
References: <20121112160451.189715188@chello.nl>
Content-Disposition: inline; filename=0003-sched-numa-mm-Add-credits-for-NUMA-placement.patch
Sender: linux-kernel-owner@vger.kernel.org
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.kernel.org

The NUMA placement code has been rewritten several times, but
the basic ideas took a lot of work to develop. The people who
put in the work deserve credit for it. Thanks Andrea & Peter :)

[ The Documentation/scheduler/numa-problem.txt file should
  probably be rewritten once we figure out the final details of
  what the NUMA code needs to do, and why. ]
