Currently the only surspace using freeze and thaw is xfs_freeze from
xfsprogs, which would work for various other filesystems that implement
->write_super_lockfs now instead of just XFS with patch 1.

The freeze stuff in this third patch isn't and won't be used by
xfs_freeze and doesn't make all that much sense (and we already had a
lot of previous discussion on this..)
