And can we afford such implementation efforts? I am generally not opposed to rustifying parts of the Linux kernel. However, I would still postpone such efforts into the future until the Rust frontend in GCC has become usable on all architectures supported by the kernel such that rustifying a kernel module does not result in it becoming unusable on architectures without a native rustc compiler.
