I don't know. Compare the following two lines:

printk(KERN_INFO "Message.\n");
kprint_info("Message.");

By dropping the lengthy macro (it's not like it's going to change
while we're running anyway, so why not make it a part of the function
name?) and the final newline, we actually end up with a net decrease
in line length.

I thought it would be nice to have something that looks familiar,
since that would ease an eventual transition. klog is a valid
alternative, but isn't kp a bit cryptic?
