I think I'm getting conflicting instructions here. IWYU is indeed what
I did: bitops, kernel, overflow, printk are all unused; string is used
only for sprintf, so I made that replacement.

However Petr said "Did anyone request the clean up, please?" which
implies to me an aversion to unwanted cleanup. So, which is it please?
