[Ocfs2-tools-devel] [patch 0/9] Add remove slots for ocfs2-tools take 4

[tao.ma at oracle.com]

tunefs.ocfs2 has been able to increase the slot for a long time.
Now the support for removing slots is also added. There are also some changes
in debugfs.ocfs2 and fsck.ocfs2 to be fit for this new feature.

Modification from v3 to v4:

1. Only check s_tunesfs_flag if FEATURE_INCOMPAT_TUNEFS is set in ocfs2_open.

2. Modify the following places in the process of removing slots.
   1) Remove relink_alloc_action enums and use existing
      INODE_ALLOC_SYSTEM_INODE instead.
   2) Limit the use of globals in the static functions.
   3) Rename new_inode to dst_blkno as it is the blkno for dst_inode.

3. Fix a bug when we remove the system file entry from the system directory.
