So we may need discussions about the different solutions here:) Hi Gerry, Thanks for working on the framework enhancement. I am still new to Linux (and learning :), but have extensive background in hot-plug features on other OS for CPU, Memory, Node, RP and PCI hot-plug support. So, I basically agree with you that we do need framework enhancement. However, I think we need phased approach here. First, we need to make CPU and Memory hot-plug work under the current framework. Once we settle on the basic features, we can then make framework enhancements without breaking the features. For CPU hotplug, I also intentionally minimized the code changes so that the changes could be back-ported to older kernels being used by distributions. I will send you more comments after I reviewed your patches (which may take some time :).
