Subject: [PATCH 24/31] sched, numa, mm: Add credits for NUMA placement
Date: Tue, 13 Nov 2012 18:13:47 +0100 [thread overview]
Message-ID: <1352826834-11774-25-git-send-email-mingo@kernel.org> (raw)
In-Reply-To: <1352826834-11774-1-git-send-email-mingo@kernel.org>
From: Rik van Riel <riel@redhat.com>
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. ]
