This new test script will create a fs with the following situations: - Preallocated extents (no data csum) - Nodatasum inodes (no data csum) - Partially written preallocated extents (no data csum for part of the extent) - Regular data extents (with data csum) And make sure after --init-csum-tree (with or without --init-extent-tree) the result fs can still pass fsck.
