The cpu<->node mappings under CONFIG_DEBUG_PER_CPU_MAPS=y when NUMA emulation is enabled is currently broken because it does not iterate through every emulated node and bind cpus that have affinity to it. NUMA emulation should bind each cpu to every local node to accurately represent the true NUMA topology of the underlying machine. debug_cpumask_set_cpu() needs to be fixed at the same time so that the debugging information that it emits shows the new cpumask of the node being assigned when the cpu is being added or removed. It can now take responsibility of setting or clearing the cpu itself to remove the need for duplicate code. Also change its last parameter, "enable", to have the correct bool type since it can only be true or false. -v2: Fix the return statements, by Kosaki Motohiro Acked-and-Tested-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Signed-off-by: David Rientjes <rientjes@google.com> Cc: Andreas Herrmann <herrmann.der.user@googlemail.com> Cc: Tejun Heo <tj@kernel.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Link: http://lkml.kernel.org/r/alpine.DEB.2.00.1104201918470.12634@chino.kir.corp.google.com Signed-off-by: Ingo Molnar <mingo@elte.hu> |
