Yes. I understood you comment and made the exact change. What I wasn't
sure about is the flow of the text in the document and if the literal
block was just missed or the entire text is supposed to be in a single
block.

I now have a real example text from /sys/kernel/debug/page_owner to
use a real example and fix the warn at the same time.
