Hum I'm not sure it should. NFS has requirement about what should
be on disk when it returns ACK to the client. NFSv3 has mechanisms
to delay writes for data (write and commit NFS operation) but I don't
remember the equivalent for metadatas.
If softdeps really helps NFS servers, then it probably breaks the reliability
model of NFS.
