* Data shared between user space and kernel space on a per cgroup
* basis. This data is shared using taskstats.

* Most of these states are derived by looking at the task->state value
* For the nr_io_wait state, a flag in the delay accounting structure
* indicates that the task is waiting on IO
*
* Each member is aligned to a 8 byte boundary.
