Hi Doug and Linus,

The move hfi1 from the staging is a right thing, it was there a long
time and it is almost ready.

However the timing of this move puzzle me, we are in the process of ABI
change [1, 2] as a response to security alert [3]. Moves like this with
proprietary char device and ABI scheme different from whole RDMA stack
will limit the ABI work without real need.

Will this driver be **forced** to adjust to new ABI scheme whenever it
comes? If it is not possible, the better solution to converge on ABI change will be
to leave this driver in staging/rdma and wait till proper solution will be accepted.

Thanks.
