16 On one hand, kernel folks wanted to keep `alloc` in-tree to have more
20 On the other hand, Rust folks wanted to keep `alloc` as close as
24 We agreed on a middle-ground: we would keep a subset of `alloc`
26 Then, upstream can start adding the functions that we add to `alloc`
28 what it needs in `alloc` and all the new methods are merged into
29 upstream, so that we can drop `alloc` from the kernel tree and go back
