The proposal to integrate Rust code into the Linux kernel has sparked intense debate among developers. While proponents, including Linus Torvalds, champion Rust for its memory safety advantages, skeptics like Christoph Hellwig fear the complications of maintaining a multi-language codebase. The discussions intensified following suggestions to enable Rust-written device drivers to interact with existing C-based APIs. Despite the establishment of a "Rust kernel policy," resistance remains, particularly among C and C++ veterans worried about their relevance in an evolving environment. Yet, many acknowledge that Rust could potentially address persistent bugs in the kernel.
Several Linux developers are concerned about adding Rust code to the kernel due to fears of increased maintenance difficulties; however, proponents argue it enhances memory safety.
Linus Torvalds stands firm on integrating Rust into the Linux kernel, despite significant pushback from some maintainers worried about multi-language complexities.
