I think that is OK, but it may be even better to list the fields by
name. Also, our multi-line comment style is:

   * Multi-line comment.

It does not matter to the end result, but I find it helps with reviewing
when the comment is added along with the function, and then expanded as
the function is changed. It helps to understand the effects of later
patches if they need to tweak comments.

I do not care that much in this instance, since we have already
discussed it, and I know what is going on, though.
