True, the proposed code is useless at this state.
Nevertheless, mana_ib team aims to send kernel ULP patches after we are done
with uverbs pathes (i.e., udata is not null). As this change does not conflict with the
current effort, I decided to send this patch now. I can extend the series to make
it more useful.

Jason, could you suggest a minimal list of ib_device_ops methods, that includes
get_dma_mr, which can be approved?

Thanks,
Konstantin
