You have the right intentions, but this patch needs some work.

This looks like a docbook comment format but isn't that format.

The first couple of lines need to be reworded to be a complete sentence like
the rest.

In general best to make new comments the same as existing comments
in the same area.

It would be better to put this description in the header file where other
docbook comments for module API are. See example around module_init() and module_exit().

Ideally, all the api's around module reference counts would be documented there.
