[Ocfs2-tools-devel] [patch 00/11] Add sparse file support in ocfs2-tools, take 2

[tao.ma at oracle.com]

The disk layout for ocfs2 volume has been changed for sparse files, so
OCFS2 Tools also need to be revised to be fit for this new feature.

The modification from V1 to V2:
1. Include the patch written by mark.
   1) Synchronize ocf2_fs.h withe the kernel.
   2) Always print out the empty extent record in debugfs.ocfs2
   3) print the e_flags field when dumping level zero extent list
      records.

2. Change mkfs.ocfs2 to be more flexible with the new features.

3. Make fsck.ocfs2 handle both sparse and non-sparse files.

4. Fix a judgement bug in debugfs.ocfs2.

5. Remove ocfs2_extent_map_init and ocfs2_extent_map_free.

6. Make ocfs2_file_write only zero the blocks outside of the
   user request.
