* In the case of WRITE, we also want to put the GETATTR after
* the operation -- in this case because we want to make sure
* we get the post-operation mtime and size. This means that
* we can't use xdr_encode_pages() as written: we need a variant
* of it which would leave room in the 'tail' iovec.

* Both of these changes to the XDR layer would in fact be quite
* minor, but I decided to leave them for a subsequent patch.
