Hmm, since we don't have to enable SYSFS for NUMA, how about make a new Kconfig for drivers/base/node.c? I.e., CONFIG_NUMA_SYSFS, like patch below.I dont quite understand this patch, nor the idea behind it. You can have a NUMA kernel (for appropriate percpu locality or whatever kernel data), and yet user land processes unable to use numactl if SYSFS is not enabled. I dont see a problem.
Both Pekka and Mel pointed out that it makes sense to have NUMA kernel without SYSFS, this means sysfs interface is not a must for NUMA kernel. Thus, I think it makes sense to separate the numa sysfs code out. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
