Yes that exactly what I meant. Just to clarify my position on XRC API. I
am not against it (even if I think that usefulness of sharing QPs between
processes is overestimated why should I be right?), I just want to be sure
that it will not be changed in a couple of month after release of OFED 1.3
because kernel people will not except it into the kernel as is.
