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..) |
