- * xfs_iomap_t: File system I/O map
- *
- * The iomap_bn field is expressed in 512-byte blocks, and is where the
- * mapping starts on disk.
- *
- * The iomap_offset, iomap_bsize and iomap_delta fields are in bytes.
- * iomap_offset is the offset of the mapping in the file itself.
- * iomap_bsize is the size of the mapping, iomap_delta is the
- * desired data's offset into the mapping, given the offset supplied
- * to the file I/O map routine.
- *
- * When a request is made to read beyond the logical end of the object,
- * iomap_size may be set to 0, but iomap_offset and iomap_length should be set
- * to the actual amount of underlying storage that has been allocated, if any.
