* small: drop function declarations without definitions * small: improve real_size calculation in small_alloc_info NO_DOC=submodule bump NO_TEST=submodule bump NO_CHANGELOG=submodule bump (cherry picked from commit 8e26d51)
The main part of the fix resides in the `small` submodule, see commit "small: improve real_size calculation in small_alloc_info". Current patch fixes the pointer that is passed to `small_alloc_info()` - it should point to the `memtx_tuple` rather than `tuple`. Also `memtx_tuple` contains `uint32_t version` that had not been accounted before, now these 4 bytes are added to the `header_size`. Closes #10217 @TarantoolBot document Title: Remove the note regarding `waste_size` from `tuple_object.info()` Product: Tarantool Root document: https://www.tarantool.io/en/doc/latest/reference/reference_lua/box_tuple/info/#box-tuple-info Remove the following note: `waste_size` is provided for reference only and can be inaccurate. Avoid using it for memory usage calculations. (cherry picked from commit 5a052bd)
