Subject: Re: [PATCH 0/3] Rust 1.68.2 upgrade

I've applied the patch series, upgraded rustc and built the kernel:

$ rustup override set $(scripts/min-tool-version.sh rustc)
$ rustup component add rust-src # Rust standard library source
$ cargo install --locked --version $(scripts/min-tool-version.sh
bindgen) bindgen
$ make LLVM=1 rustavailable
$ grep  RUSTC_VERSION .config
CONFIG_RUSTC_VERSION_TEXT="rustc 1.68.2 (9eb3afe9e 2023-03-27)"
$ make LLVM=1 -j$(nproc)

Then I ran the kernel in qemu-system-x86_64, inserted the
rust_minimal.ko kernel module and checked that it behaves as expected.

Tested-by: Ariel Miculas <amiculas@...co.com>

Cheers,
Ariel
