Subject: What should the server do for LAYOUTRETURN with lrf_length==0
Content-Type: text/plain; charset=ISO-8859-1
Sender: linux-nfs-owner@vger.kernel.org
List-ID: <linux-nfs.vger.kernel.org>

Since no bytes are covered in this case the spec. appears to indicate that the
server will just be silent about that and do nothing.  However a 0 length return
doesn't make much sense so would we like the server to return NFS4ERR_INVAL instead?
