Thanks for an excellent article.

I want to know how to test whether a given driver module is SMP safe and pre-emption safe or not?

typo: preempt_enable_noresched()

should be preempt_enable_no_resched()

I want to start off by saying how much I appreciate these series of articles. Thank you!

I haven't even come close to using 2.5 yet, but I have been using kernels >= 2.4.18 with the RML preempt patch. Is this patch the same or pretty close to the preemptible code in the 2.5.xx kernels?
