+ * preparing its contents to be copied into the cache image block.
+ *
+ * Some fields are also used in loading the contents of the metadata cache

+ * either protected by the library (at which point they become regular
+ * entries) or are evicted. See discussion of the prefetched field for
+ * further details.
+ *
+ * include_in_image: Boolean flag indicating whether this entry should
+ * be included in the metadata cache image. This field should
+ * always be false prior to the H5C_prep_for_file_close() call.
+ * During that call, it should be set to TRUE for all entries
+ * that are to be included in the metadata cache image. At
+ * present, only the superblock, the superblock extension
+ * object header and its chunks (if any) are omitted from
+ * the image.
+ *
+ * lru_rank: Rank of the entry in the LRU just prior to file close.
+ *
+ * Note that the first entry on the LRU has lru_rank 1,
+ * and that entries not on the LRU at that time will have
+ * either lru_rank -1 (if pinned) or 0 (if loaded during

+ * image_dirty: Boolean flag indicating whether the entry should be marked
+ * as dirty in the metadata cache image. The flag is set to
+ * TRUE iff the entry is dirty when H5C_prep_for_file_close()
+ * is called.
+ *
+ * fd_parent_count: If the entry is a child in one or more flush dependency
+ * relationships, this field contains the number of flush
+ * dependency parents.
+ *
+ * In all other cases, the field is set to zero.
+ *
+ * Note that while this count is initially taken from the

+ *
+ * Finally observe that if the entry is dirty and in the
+ * cache image, and its parent is dirty and not in the cache
+ * image, then the entry must be removed from the cache image
+ * to avoid violating the flush dependency flush ordering.
+ *
+ * fd_parent_addrs: If the entry is a child in one or more flush dependency
+ * relationship when H5C_prep_for_file_close() is called, this
+ * field must contain a pointer to an array of size
+ * fd_parent_count containing the on disk addresses of the
+ * parent.
+ *
+ * In all other cases, the field is set to NULL.
+ *
+ * Note that while this list of addresses is initially taken

+ * that are not in the image are removed from this list, and
+ * and from the fd_parent_count above.

+ * image, then the entry must be removed from the cache image
+ * to avoid violating the flush dependency flush ordering.
+ *
+ * fd_child_count: If the entry is a parent in a flush dependency
+ * relationship, this field contains the number of flush
+ * dependency children.
+ *
+ * In all other cases, the field is set to zero.
+ *
+ * Note that while this count is initially taken from the
+ * flush dependency fields above, if the entry is in the
+ * cache image (i.e. include_in_image is TRUE), any children
+ * that are not in the image are removed from this count.
+ *
+ * fd_dirty_child_count: If the entry is a parent in a flush dependency
+ * relationship, this field contains the number of dirty flush
+ * dependency children.
+ *
+ * In all other cases, the field is set to zero.
+ *
+ * Note that while this count is initially taken from the
+ * flush dependency fields above, if the entry is in the
+ * cache image (i.e. include_in_image is TRUE), any dirty
+ * children that are not in the image are removed from this
+ * count.
+ *
+ * image_fd_height: Flush dependency height of the entry in the cache image.
+ *
+ * The flush dependency height of any entry involved in a
+ * flush dependency relationship is defined to be the
+ * longest flush dependency path from that entry to an entry
+ * with no flush depenency children.
+ *
+ * Since the image_fd_height is used to order entries in the
+ * cache image so that fd parents preceed fd children, for
+ * purposes of this field, and entry is at flush dependency
+ * level 0 if it either has no children, or if all of its
+ * children are not in the cache image.
+ *
+ * Note that if a child in a flush dependency relationship is
+ * dirty and in the cache image, and its parent is dirty and
+ * not in the cache image, then the child must be excluded
+ * from the cache image to maintain flush ordering.
+ *
+ * prefetched: Boolean flag indicating that the on disk image of the entry
+ * has been loaded into the cache prior any request for the
+ * entry by the rest of the library.
+ *
+ * As of this writing (8/10/15), this can only happen through
+ * the load of a cache image block, although other scenarios
+ * are contemplated for the use of this feature. Note that
+ * unlike the usual prefetch situation, this means that a
+ * pre fetched entry can be dirty, and/or can be a party to
+ * flush dependency relationship(s). This complicates matters
+ * somewhat.
+ *
+ * The essential feature of a pre-fetched entry is that it
+ * consists only of a buffer containing the on disk image of
+ * the entry. Thus it must be deserialized before it can
+ * be passed back to the library on a protect call. This
+ * task is handled by H5C_deserialized_prefetched_entry().
+ * In essence, this routine calls the deserialize callback
+ * provided in the protect call with the on disk image,
+ * deletes the prefetched entry from the cache, and replaces
+ * it with the deserialized entry returned by the deserialize
+ * callback.
+ *
+ * Further, if the prefetched entry is a flush dependency parent,
+ * all its flush dependency children (which must also be
+ * pre-fetched entries), must be tranfered to the new cache
+ * entry returned by the deserailization callback.
+ *
+ * Finally, if the prefetched entry is a flush dependency child,
+ * this flush dependency must be destroyed prior to the
+ * deserialize call.
+ *
+ * In addition to the above special processing on the first
+ * protect call on a prefetched entry (after which is no longer
+ * a prefetched entry), prefetched entries also require special
+ * tretment on flush and evict.
+ *
+ * On flush, a dirty prefetched entry must simply be written
+ * to disk and marked clean without any call to any client
+ * callback.
+ *
+ * On eviction, if a prefetched entry is a flush dependency
+ * child, that flush dependency relationship must be destroyed
+ * just prior to the eviction. If the flush dependency code
+ * is working properly, it should be impossible for any entry
+ * that is a flush dependency parent to be evicted.
+ *
+ * prefetch_type_id: Integer field containing the type ID of the prefetched
+ * entry. This ID must match the ID of the type provided in any
+ * protect call on the prefetched entry.
+ *
+ * The value of this field is undefined in prefetched is FALSE.
+ *
+ * age: Number of times a prefetched entry has appeared in
+ * subsequent cache images. The field exists to allow
+ * imposition of a limit on how many times a prefetched
+ * entry can appear in subsequent cache images without being
+ * converted to a regular entry.
+ *
+ * This field must be zero if prefetched is FALSE.
+ *
+ * serialization_count: Integer field used to maintain a count of the
+ * number of times each entry is serialized during cache
+ * serialization. While no entry should be serialized more than
+ * once in any serialization call, throw an assertion if any
+ * flush depencency parent is serialized more than once during
+ * a single cache serialization.
+ *
+ * This is a debugging field, and thus is maintained only if
+ * NDEBUG is undefined.
