| |
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. ]
