When multiple kernel threads are created to cooperatively work on
a common task, we may need a convenient way to access data that are
specific to each kthread.
The kthread_data() function fits this need. However, it was not
visible to kthreads started in a kernel module. To solve this problem,
the kthread_data() function is now exported allowing kthreads from
kernel modules to use it.
