What is a Kernel thread?

Question

i am just started coding of device driver and new to threading, went through many documents for getting an idea about threads. i still have some doubts.

Answer 1

A kernel thread is a kernel task running only in kernel mode; it usually has not been created by fork() or clone() system calls. An example is kworker or kswapd.

You probably should not implement kernel threads if you don't know what they are.

Google gives many pages about kernel threads, e.g. Frey's page.
