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. ] Signed-off-by: Rik van Riel Acked-by: Peter Zijlstra Cc: aarcange@redhat.com Cc: Linus Torvalds Cc: Andrew Morton Link: http://lkml.kernel.org/r/20121018171928.24d06af4@cuia.bos.redhat.com Signed-off-by: Ingo Molnar ---- This is against tip.git numa/core --- diff --git a/CREDITS b/CREDITS index d8fe12a9421f..b4cdc8f2971a 100644 --- a/CREDITS +++ b/CREDITS @@ -125,6 +125,7 @@ D: Author of pscan that helps to fix lp/parport bugs D: Author of lil (Linux Interrupt Latency benchmark) D: Fixed the shm swap deallocation at swapoff time (try_to_unuse message) D: VM hacker +D: NUMA task placement D: Various other kernel hacks S: Imola 40026 S: Italy diff --git a/kernel/sched/fair.c b/kernel/sched/fair.c index bfe07cd7f827..3e51cfd9d1c1 100644 --- a/kernel/sched/fair.c +++ b/kernel/sched/fair.c @@ -18,6 +18,9 @@ * * Adaptive scheduling granularity, math enhancements by Peter Zijlstra * Copyright (C) 2007 Red Hat, Inc., Peter Zijlstra + * + * NUMA placement, statistics and algorithm by Andrea Arcangeli, + * CFS balancing changes by Peter Zijlstra.
