[ofa-general] OFED July 2, meeting summary on next OFED plans

[Roland Dreier]

 > NFSoRDMA integration.

I would like to see a status report on NFS/RDMA from the people who
want it in OFED.  As I understand it there are many core kernel
changes required for this -- switchable transports and also mount
option changes?

As far as I can tell from the outside, the NFS/RDMA effort seems to
have stalled -- whenever I talk to core NFS developers like Chuck
Lever or Trond Myklebust, they say that they are just waiting for the
NFS/RDMA developers to submit their changes for review.  And I haven't
seen any patches for a kernel newer that 2.6.18, so things look quite
out-of-date.

Without visible progress towards getting NFS/RDMA into mergeable form
soon, I think putting it into OFED 1.3 as anything other than a
technology preview that may be dropped from future releases would be a
very risky think to do.  Otherwise OFED risks getting stuck
maintaining the whole NFS/RDMA stack, since the development effort
outside of OFED really looks to me like it is fizzling out.
