Yeah, that sounds good to me. It is clear and we don't use "errno"
elsewhere. This identifier came from the original import, so before we
started to think about naming policies.

Though perhaps we can clean it up in a patch later, since we should
change `to_kernel_errno` below too at the same time. Or if you want to
send a quick patch for that one, I can put it in first.

Cheers,
Miguel
