        [PATCH] revert blockdev direct io back to 2.6.19 version
    
        Andrew Vasquez is reporting as-iosched oopses and a 65% throughput
        slowdown due to the recent special-casing of direct-io against
        blockdevs.  We don't know why either of these things are occurring.
    
        The patch minimally reverts us back to the 2.6.19 code for a 2.6.20
        release.
    
    <--  snip  -->
    
    It has since been dead code, and unless someone wants to revive it now
    it's time to remove it.
    
    This patch also makes bio_release_pages() static again and removes the
    ki_bio_count member from struct kiocb, reverting changes that had been
    done for this dead code.
