AFAIK, What you're talking about is a kernel compiled with "voluntary" preemption.. Isn't it true that in non-voluntary preemption (CONFIG_PREEMPT=y), the kernel execution itself can be preempted/interrupted when it is not in a spin lock guarded critical region? And since we're talking about sleeping, we're not in a critical region anyway (we're not supposed sleep in these AFAIK) Let me know your thoughts & Thanks, -Joel -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecar...@nl.linux.org Please read the FAQ at http://kernelnewbies.org/FAQ
