The first patch adds a --data flag, and prints a line about data being read by NFS

The second patch adds a line about write data. I'm not quire sure about this patch. I'm seeing oddities where the number of bytes in "NORMALWRITTENBYTES + DIRECTWRITTENBYTES" does not equal SERVERWRITTENBYTES. In some cases the amount of data written by the app (normalwrittenbytes + directwrittenbytes) is greater than the amount of data written to the server, and in other cases it's less than the amount of data written to the server. At the moment, i've ascribed that difference to data being written to the local cache and not flushed, but that doesn't make a whole lot of sense.
