Of course, I'm not planning to add pr_debug() all over the kernel.

When I need to print something to consoles, I will use one-time patch
(like https://syzkaller.appspot.com/text?tag=Patch&x=135f254a100000 ) for
adding custom printk() and turning on some switches for making existing
printk() calls work.
