Why not just > depend on CONFIG_PRINTK for now? I was thinking about that, but I figured it is probably easier in the long run to make sure it always works without printk. It also just seemed like the right thing to do, but I suppose that's not a very good reason. I am fine with any of the three options: depend on CONFIG_PRINTK - as suggested by Stephen, just use printk - as suggested by Shuah, or continue to use vprintk_emit as I have been doing. However, my preference is the vprintk_emit option. Anyone have any strong opinions on the matter?
