In message <20030718003944.A10817@vaasje.org>, you said:
;NetBSD currently does not preempt processes while they're in the kernel,
;so it seems to me that you can simply define these primitives as no-ops.
You mean that if a kernel thread created with a call kthread_create1()
will run until it volunteerly yields the CPU? It won't get preempted?
crap. The threads I need to mark preemptable or not have no
association with user space, they are born and die entirely in the
I looked, but I don't see where the kernel makes the decision not
to reschedule a process which is executing in kernel space.
If this is really true I have another problem. Is there a way to
make kernel threads preemptable?
