* nilfs_btree_convert_and_insert - Convert and insert entries into a B-tree
* @btree: NILFS B-tree structure
* @key: Key of the new entry to be inserted
* @ptr: Pointer (block number) associated with the key to be inserted
* @keys: Array of keys to be inserted in addition to @key
* @ptrs: Array of pointers associated with @keys
* @n: Number of keys and pointers in @keys and @ptrs
*
* This function is used to insert a new entry specified by @key and @ptr,
* along with additional entries specified by @keys and @ptrs arrays, into a
* NILFS B-tree.
* It prepares the necessary changes by allocating the required blocks and any
* necessary intermediate nodes. It converts configurations from other forms of
* block mapping (the one that currently exists is direct mapping) to a B-tree.
*
* Return: 0 on success or a negative error code on failure.
