Re: [PATCH v5 18/44] cache-tree: introduce write_index_as_tree()

> A caller may wish to write a temporary index as a tree. However,
> write_cache_as_tree() assumes that the index was read from, and will
> write to, the default index file path. Introduce write_index_as_tree()
> which removes this limitation by allowing the caller to specify its own
> index_state and index file path.
