    Note that writepage() doesn't get used much. Most VM-initiated
    filesystem writeback activity is via try_to_release_page(), which
    has somewhat more vague and flexible semantics.

    And by bdflush, which I suspect tends to conflict with sync_page_buffers()
    under pressure. But that's a different problem.
