OK, I use spin_lock_irqsave first, and then I only use spin_lock when I already know interrupts are off. But the locks I usually use are used by interrupts and that is reason enough to use it. I wouldn't use the _irqsave for simplicity, I use it since I still believe it keeps latency down for SMP.

Naw, I'm doing my PhD on implemting Linux drivers in SmallTalk. That will make everybody happy!
