Another question: the "preempt_disable/enable()" around the use of the
per-cpu vprintk_func thing seems dubious.
Why do I say that? I think it cannot possibly make sense. Anybody who
sets that function pointer to any per-cpu value has to disable
preemption for that to make sense, so doing it inside the printk()
paths seems dubious at best.
No?
