From 392e34b6bc22077ef63abf62387ea3e9f39418c1 Mon Sep 17 00:00:00 2001 From: Danilo Krummrich Date: Fri, 4 Oct 2024 17:41:32 +0200 Subject: kbuild: rust: remove the `alloc` crate and `GlobalAlloc` Now that we have our own `Allocator`, `Box` and `Vec` types we can remove Rust's `alloc` crate and the `new_uninit` unstable feature. Also remove `Kmalloc`'s `GlobalAlloc` implementation -- we can't remove this in a separate patch, since the `alloc` crate requires a `#[global_allocator]` to set, that implements `GlobalAlloc`.
