I'm not sure why this one struct has an actual description that
resembles kerneldoc, when nothing else does - but why not make it
actually kerneldoc, as you're almost there as things stand:

^^ also your mail client is doing some really odd things wrapping wise.

It does:

The patchwork automation seems to have ignored this patchset for some
reason. It was stuck on a patchset for some reason and this one may
have got skipped when I tried to sort that out.
Ordinarily, you'd see it complaining about these sorts of things.

Thanks,
Conor.
