 KernelStack and UserStack.

Everything about task management, like starting and switching tasks is implemented here.

A single global instance of TaskManager called TASK_MANAGER controls all the tasks in the operating system.

Be careful when you see __switch ASM function in switch.S. Control flow around this function might not be what you expect.
