    Hi Trond,
    Your fix to nfs_readpage_result worked. There may be a small hole
    remaining, which the following closes. This also worked.

    - if (data->res.eof || page_index(page) <= inode->i_size >> PAGE_CACHE_SHIFT)
    + if (data->res.eof || page_index(page) < PAGE_CACHE_ALIGN(inode->i_size) >> PAGE_CACHE_SHIFT)

    Thanks for your help,
    (I'll leave it to you to submit the patch you think best to Marcello and/or Linus).
    Joe
