OK. Say I'm a scraper.  How do I distinguish between:

pr_info("foo");
printk(KERN_INFO "foo");

Oh my. seems that both result in exactly the same thing ending up in the
dmesg buffer

No it doesn't result in the same output, read the definitions again.

pr_info can be influenced by pr_fmt, plain printk cannot
