Currently, the Rust build doesn't work throughout the entire series
since there are some commits where krealloc is missing before you
introduce the helper. If you introduce the helper first before
krealloc stops being an exported function, then the Rust build should
work throughout the entire series. (Having both the helper and the
exported function at the same time is not a problem.)
