    OK. So with that patch, nfs_writepages() may still leave I/O pending,
    uninitiated, yes?

    I don't understand why NFS hasn't been BUGging as it stands at present. It
    has several end_page_writeback() calls but no set_page_writeback()s.
    end_page_writeback() or rotate_reclaimable_page() will go BUG if the page
    wasn't PageWriteback().
