An alternative (possibly cleaner) would be: 1) add a css_size field in cgroup_subsys that contains the size of the per-subsystem structure 2) change cgroups to allocate and populate the css *before* calling create(), since it now knows the actual size 3) simplify all the subsystem create() methods since they no longer have to worry about allocation or out-of-memory handling 4) also add a top_css field in cgroups that allows cpusets to use the statically-allocated top_cpuset since it's initialized prior to memory allocation being reliable This avoids us having to pass in any new parameters to the create() method in future since they can be populated in the CSS.
