Sure, I truly believe that we can do common API in a months time-frame
and I want to be focused on one transition path only (write/read -> new
API) and not on two parallel paths (ioctl -> new API and write/read ->
new API) plus support of all these intermediate steps.

The original request came after this driver was moved from staging to
RDMA stack, since the driver is still in staging, there is no need to
hurry up now.
