Various structures embed a struct cgroup_subsys_state, typically at the top of the containing structure. It is common for code that accesses the structures to perform operations that iterate over the chain of parent css pointers, also accessing data in each containing structure. In particular, struct cpuacct is used by fairly hot code paths in the scheduler such as cpuacct_charge(). Move the parent css pointer field to the end of the structure to increase the chances of residing in the same cache line as the data from the containing structure.
