This thread is pointless. The next patch converts it to atomic64_t and the lock is removed anyway. I think Eric's argument makes sense given that atomic64_t translates into irqsave spinlock (it has to) in generic 32bit implementation. That said, this is all a moot point. We might as well simply drop this patch and directly convert to atomic64_t.
