I was looking for the short and sweet overview such as you just presented ;). Thanks. I need to start following this hotplug work because it is next door to the cpu/memory placement work that I am most focused on, such as cpusets, led by Simon Derr of Bull, sitting on top of sched_setaffinity and Andi Kleen's numa work. A cpuset is a set of cpu and memory resources that several tasks share, perhaps exclusively (all other tasks kept out). At some point, questions such as "what happens when a node is unplugged from a cpuset" will need to be answered. And even earlier, "what happens when a cpu is unplugged that was in a tasks cpus_allowed, or a memory node unplugged, that was in a vma's list of allowed memory zones." Or perhaps the answers to these questions are already known ?? -- I won't rest till it's the best ...
