    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.
