The current patch series from Jeff helps with the stable handle problem, which is an important one, although maybe not the one you and Amir care about most. I care about it most, because the addition of unstable handles caused problems and I really want that fixed before it spreads further, and I think anything mentioning NFS in that is factually wrong. If we need additional flags to work around other issues (as in the list compiled by Neil) I'd still prefer them to be named about what issues they deal with, but folks get too tired of that I could probably with a "NFSD get the f^&&& out" name if we'd just keep shouting at each other otherwise.
