Killing kernel threads

[Super user]

Hi,

Is there any guaranted way to kill kernel threads
started from loadable modules. I've written a kernel
module that starts 8 kernel threads and sometimes one
of them goes into uninterruptible sleep. Is there
anyway to flush away such threads while unloading
modules.

I've tried using kill_proc with SIGKILL but it doesn't
seem to help.

BTW, I am using the code for handling kernel threads
at http://www.scs.ch/~frey/linux/kernelthreads.html

Any pointers regarding the same are highly
appreciated.

Thanks,
