As I've said before, my only requirement is that we hold off on merging optional 4.1 features (like pNFS) until the *mandatory* parts of 4.1 comply with the spec. Once that happens, I'm happy to help with merging pNFS however I can, including working out any VFS problems. Most of us have been assuming that the GFS2-backed server would be the simplest to merge first, but with the client supporting all three layout types, maybe it would be reasonable to start with the exofs-backed server if that's in better shape. To help the process along I'm continuing to maintain a 4.1 todo list: http://wiki.linux-nfs.org/wiki/index.php/Server_4.0_and_4.1_issues#Highest_priority I believe that could all be done relatively soon with some more help. --b. > But it is there and alive in full open-source glory in Benny's tree. > > > I'm less worried about this now than I was earlier, because other open > > source efforts are gaining traction (see Ganesha - which is being > > sponsored by IBM, and projects such as Tigran's java based pNFS server). > > The other point is that we've developed client test-rigs that don't > > depend on the availability of a Linux server (newpynfs and the pynfs > > based proxy). > > > > For me I'm testing with the linux Server and it is just there and works > well for me.
