This is just a resend of the previous series at
https://lore.kernel.org/patchwork/patch/1014892/
with a small if block refactor as Andy suggested:
https://lore.kernel.org/patchwork/comment/1198679/

All,
Could you please provide your Reviewed-by / Acked-by tags?

I will also resend the manpage changes shortly.
