Thanks for the comment, Jakub.

There is no technical limitation. I didn't include SET support simply to keep
the initial series minimal as possible.

However, you're right, adding such a module parameter would also make it part of
the uAPI and unnecesarily hard to remove later. It's better to implement SET
from the beggining.

Dave, let me respin the series with SET support and drop the module parameter.
Please let me know if you have any objections.

Best regards,
Koichiro
