commit ac10d67fef2d3dcacbe0d8a810738b06dcc63d0f
Author: Srinivas Eeda <srinivas.eeda at oracle.com>
Date:   Thu May 15 17:21:55 2008 -0700

    Adds o2image header and supporting functions
    
    o2image - An ocfs2 tool to save critical ocfs2 filesystem metadata to a
    specified image-file. Image-file may be examined using debugfs.ocfs2 or
    may be used to restore using o2image. Image-file can be of two formats:
    
    1. Packed - This format(default) contains a o2image header, packed
    metadata blocks and a bitmap.
    2. raw    - A raw image is a sparse file containing the metadata blocks.
    
    Usage: o2image [-rI] <device> <imagefile>
    
    Packed format contains bitmap towards the end of the image-file. Each bit in
    the bitmap represents a block in the filesystem.
    
    When the packed image is opened using o2image or debugfs.ocfs2, bitmap is
    loaded into memory and used to map disk blocks to image blocks.
    
    Raw image is a sparse file containing metadata blocks at the same offset as
    the filesystem.
    
    debugfs.ocfs2 is modified to detect image-file when the image-file is
    specified with -i option.
    
    This patch adds o2image header files and supporting functions to read
    write to image-file
