Subject: [PATCH 3/8] sched, numa, mm: Add credits for NUMA placement
Date: Mon, 12 Nov 2012 17:04:54 +0100 [thread overview]
Message-ID: <20121112161215.584642205@chello.nl> (raw)
In-Reply-To: 20121112160451.189715188@chello.nl
[-- Attachment #1: 0003-sched-numa-mm-Add-credits-for-NUMA-placement.patch --]
[-- Type: text/plain, Size: 2248 bytes --]
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. ]
