Greg has already asked you to resend. So here follow a few remarks to
take into account for that resend.

That symbol doesn't exist and is not added in this series, right? If so,
scripts/checkkconsymbols.py could have told you that.

This states the license is GPL v2.

I couldn't spot any users of these exports. Actually, I couldn't even
spot any users of these three functions. Why were they added?

This states, according to include/linux/module.h, that the license is
GPL v2 or later. So I think either the comment at the top of this file
or the ident used in the MODULE_LICENSE() macro needs to change.
