The zpool checkpoint feature in DxOS added a new field in the uberblock. The Multi-Modifier Protection Pull Request from ZoL adds two new fields in the uberblock (Reference: https://github.com/zfsonlinux/zfs/pull/6279).
As these two changes come from two different sources and once upstreamed and deployed will introduce an incompatibility with each other we want to upstream a change that will reserve the padding for both of them so integration goes smoothly and everyone gets both features.
