Kernel threads without process context

[Michael Neumann]

Hi,

Are there any kernel threads without process context? Which ones are
those and for what reason don't they have a process context?

Regards,

   Michael

The pageout daemon is one of such threads [1].

    Most kernel threads do not have processes.  If you do a 'ps axl', any
    process you see with a PID of -1 is a pure kernel thread.
