The printk() troubles are not only about the "high volume" vs. "very
important", but also about the context of the caller.
The optimistic comment above printk() says that it can be called from any
context, but that's not true for quite some time already.
So if printk() is going to be redesigned to be more lightweight, this
aspect definitely needs to be taken into consideration as well.
