rust: kbuild: allow `unused_features`

2026-03-19T15:15:01Z

commit 592c61f3bfceaa29f8275696bd67c3dfad7ef72e upstream. Starting with the upcoming Rust 1.96.0 (to be released 2026-05-28), `rustc` introduces the new lint `unused_features` [1], which warns [2]: warning: feature `used_with_arg` is declared but not used --> :1:93 | 1 | #![feature(asm_const,asm_goto,arbitrary_self_types,lint_reasons,offset_of_nested,raw_ref_op,used_with_arg)] | ^^^^^^^^^^^^^ | = note: `#[warn(unused_features)]` (part of `#[warn(unused)]`) on by default The original goal of using `-Zcrate-attr` automatically was that there is a consistent set of features enabled and managed globally for all Rust kernel code (modulo exceptions like the `rust/` crated). While we could require crates to enable features manually (even if we still keep the `-Zallow-features=` list, i.e. removing the `-Zcrate-attr` list), it is not really worth making all developers worry about it just for a new lint. The features are expected to eventually become stable anyway (most already did), and thus having to remove features in every file that may use them is not worth it either. Thus just allow the new lint globally. The lint actually existed for a long time, which is why `rustc` does not complain about an unknown lint in the stable versions we support, but it was "disabled" years ago [3], and now it was made to work again. For extra context, the new implementation of the lint has already been improved to avoid linting about features that became stable thanks to Benno's report and the ensuing discussion [4] [5], but while that helps, it is still the case that we may have features enabled that are not used for one reason or another in a particular crate.

kbuild: Leave objtool binary around with 'make clean'

2026-03-12T11:09:39Z

commit fdb12c8a24a453bdd6759979b6ef1e04ebd4beb4 upstream. The difference between 'make clean' and 'make mrproper' is documented in 'make help' as: clean - Remove most generated files but keep the config and enough build support to build external modules mrproper - Remove all generated files + config + various backup files After commit 68b4fe32d737 ("kbuild: Add objtool to top-level clean target"), running 'make clean' then attempting to build an external module with the resulting build directory fails with $ make ARCH=x86_64 O=build clean $ make -C build M=... MO=... ... /bin/sh: line 1: .../build/tools/objtool/objtool: No such file or directory as 'make clean' removes the objtool binary. Split the objtool clean target into mrproper and clean like Kbuild does and remove all generated artifacts with 'make clean' except for the objtool binary, which is removed with 'make mrproper'. To avoid a small race when running the objtool clean target through both objtool_mrproper and objtool_clean when running 'make mrproper', modify objtool's clean up find command to avoid using find's '-delete' command by piping the files into 'xargs rm -f' like the rest of Kbuild does.
