CPU sockets are represented by NUMA nodes. We need three layers of scheduler grouping, and those are the three layers provided by the kernel's generic hierarchy: NUMA node --> physical_package --> core Inside the CPU socket we need two layers of scheduler grouping, so that's how I decided to implement things. So it's intentional and on purpose. -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
