What are the relations between a kernel control path a kernel thread?

Understanding The Linux Kernel says:

A kernel control path denotes the sequence of instructions executed by the kernel to handle a system call, an exception, or an interrupt.

and

Besides user processes, Unix systems include a few privileged processes called kernel threads with the following characteristics:

• They run in Kernel Mode in the kernel address space.

• They do not interact with users, and thus do not require terminal devices.

• They are usually created during system startup and remain alive until the system is shut down.

1. What are the relations between the two concepts: a kernel control path a kernel thread?

   Is a kernel control path a kernel thread?

   Is a kernel thread a kernel control path?

2. If I am correct, a kernel thread is represented as a task_struct object.

   So is a kernel control path?
   If not, what kinds of kernel control paths can be and what kinds can't be?

3. If I am correct, a kernel thread can be scheduled together with processes.

   Can a kernel control path? If not, what kinds of kernel control paths can be and what kinds can't be?
