    Ok, I retried my test without the filemap_write_and_wait() that is not
    protected by i_sem and the test still sees uninitialized data. I'm
    still running with test10-mm1 + all the patches I sent out before.
    I'm haven't tried 2.6.0-rc*-mm1 yet. I need to move all my debug code
    over to the latest mm kernel. I also did not want to change too much
    at same time.
