SubjectRe: Preempting kernel tasks
   From: Jason Burrell <jburrell@crl.com>

Forgive me for my ignorance, but how can a kernel task be preempted?

No, under linux a kernel thread of execution can only give up the cpu
explicitly.

(btw, kernel preemption IMHO is a sorry and dirty solution for the
problem that it claims to solve)

I would suggest putting your encryption daemon task in userland and
have it block on some sort of file (/dev/whatever) and it will process
the encryption as it wakes up due to data being available from that
"file".

Later,
