They do ... you just have to mount cpusets to see it ;). If your kernel is configured with CONFIG_CPUSETS, then there is one 'top' cpuset containing all tasks, all mems, and all cpus, setup during the kernel init boot code, unconditionally. Anyone who does: mkdir -p /dev/cpuset mount -t cpuset cpuset /dev/cpuset can see it and play with it. ... perhaps I misunderstood your comment? -- I won't rest till it's the best ...
