We have an engineer assigned to rewriting the ion memory driver to use
dma_buf interfaces. Hopefully that effort will solve the problem of
requiring these interfaces to be exported so that that driver (and
others) can be modularized.

Thanks for the reviews, drop this patch from the list and we will
regroup, and accept that standing code in the kernel can not be
modularized for the moment.

Sincerely -- Mark Salyzyn
