ghost_multi_hole00 and ghost_multi_hole01 are tests which create a ghost file with a lot of holes, there are 4K data and 4K hole inside every 8K length. The only difference between them is ghost-fiemap option, 01 is a test for the fiemap dumping algorithm, and we want to test the behavior of EXTENT_MAX_COUNT part, so the file size should be 8M, thus there will be 1024 chunks in the ghost file. In some file system, such as xfs, we somehow can not easily create highly sparse file as in ext4 or btrfs, therefore we need `fallocate` to forcibly create holes.
