If I understood Yan, he is trying to use NFS/RDMA in guests (kvm?).  We
are pretty sure that is not working at the moment, but that is a priority
to get fixed. Shirley has a lab set up and has been looking into it.

So, first step would be to set up v3.15-rc3 on bare metal.

I think the critical stability patches for both client and server are
already upstream, unless you are exporting tmpfs.

The patches I just posted fix some other issues, feel free to apply them.
But the basics should be working now in v3.15-rc3.
