One more thing: the goal is to change the filesystem uuid, the chunk tree uuid should be changed as well. But I think both uuids have to be changed at the same time and the chunk tree uuid should be generated randomly as it's entirely internal value. > To avoid such problem, we introduce new btrfs super flags: > BTRFS_SUPER_FLAG_CHANGING_FSID and BTRFS_SUPER_FLAG_CHANGING_CHUNK_TREE_ID Based on that, the separate BTRFS_SUPER_FLAG_CHANGING_CHUNK_TREE_ID flag does not make sense and could be dropped. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
