I'm happy to forward this note from Trond that the NFS/RDMA kernel client will be available in the mainline after the 2.6.24-rcX process begins, among other NFS improvements of course.
There is a new nfs-aware mount command required to actually invoke an NFS/RDMA mount. The easiest way to accomplish this is to fetch the latest nfs-utils from <git://linux-nfs.org/nfs-utils> and to invoke the mount.nfs binary directly. I'll forward more details later.
