IMHO, it means that (in the following order):
1. get the task_struct ( you probably already know this)
2. get its stack property (you probably already know this too :) )
And that's it. That's the function of task_thread_info() macro: to
return the stack area of that task. IIRC too, stack area is where
thread_info belongs to.
