This new experimental data dump feature will dump the whole image, not only the existing tree blocks but also all its data extents(*). This feature will rely on the new dump format (_DUmP_v1), as it needs extra large extent size limit, and older btrfs-image dump can't handle such large item/cluster size. Since we're dumping all extents including data extents, for the restored image there is no need to use any extra super block flags to inform kernel. Kernel should just treat the restored image as any ordinary btrfs. This new feature will be hidden behind the experimental features, that's to say, if --enable-experimental is not enabled, although we still have the option, it will not do anything but output an error message. *: The data extents will be dumped as is, that's to say, even for preallocated extent, its (meaningless) data will be read out and dumpped. This behavior will cause extra space usage for the image, but we can skip all the complex partially shared preallocated extent check.
