In general, it's difficult to get locking right, especially when you start mixing multiple locks on related resources. Personally, I'd go with a simpler scheme here. There's not much value in protecting this counter with a spinlock when the other parts need to be protected by a mutex. If you do decide to do it with multiple locks, then please do document in comments how the locking is expected to work. An alternate scheme might be to consider doing this with krefs, but I haven't really considered whether that idiom makes sense here.
Jeff, please, have a look at my answer to Bryan Schumaker.
