MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Sender: linux-nfs-owner@vger.kernel.org List-ID: Hi, Presumably Linux client and server implementations would restrict use of "system." Perhaps would be more to talk about, if xattrs were implemented experimentally. I'm interested in knowing about patches that might be floating around for the Linux client, for NFSv4.x. (I've seen NFSv3 work.)
