You are welcome! The versions I'm using are listed in
scripts/min-tool-version.sh, and I have tested Rust samples and the
rnull block driver.

llvm: main branch (ea3c7b3397f8de8e885ea7cd1ed5138ec4a72d50)
rustc: 1.74.1
bindgen: 0.65.1

Here are the build steps:

1. Build llvm
2. Install rust, rust-src (using rustup) and bindgen
3. Build kernel

For more details, refer to Documentation/rust/quick-start.rst; there
is nothing special about it.

Regards,
Rui
