Well, this probably means I have done a rather poor marketing.

I assume this code is sitting in *your* tree?  How do you think it gets
into mainline?

There is no automatic way that code from linux-next gets merged into
mainline.  That is up to the tree owner to make happen, either by getting
their tree into a parent maintainers tree, or if there is none, asking
Linus to pull your tree at the appropriate time.
