Thu, 19 Mar 2026 10:35:28 +0100

rust: pin-init: replace `addr_of_mut!` with `&raw mut``feature(raw_ref_op)` became stable in Rust 1.82.0 which is the currentMSRV of pin-init with no default features. Earlier Rust versions willnow need to enable `raw_ref_op` to continue to work with pin-init.This reduces visual complexity and improves consistency with existingreference syntax.Suggested-by: Benno Lossin Link: https://github.com/Rust-for-Linux/linux/issues/1148Closes: https://github.com/Rust-for-Linux/pin-init/issues/99Signed-off-by: Antonio Hickey Link: https://github.com/Rust-for-Linux/pin-init/commit/e27763004e2f6616b089437fbe9b3719cd72bd5c[ Reworded commit message. - Benno ]Reviewed-by: Gary Guo Link: https://patch.msgid.link/20260319093542.3756606-6-lossin@kernel.orgSigned-off-by: Benno Lossin List of files: /linux/rust/pin-init/examples/pthread_mutex.rs

Thu, 19 Mar 2026 10:35:24 +0100

rust: pin-init: build: simplify use of nightly featuresWe use some features that are already stable in later versions of Rust,but only available as unstable features in older Rust versions that thekernel needs to support.Instead of checking if a feature is already stable, simply enable themand allow the warning if the feature is already stable. This avoids theneed of hardcoding whether a feature has been stabilized at a givenversion.`#[feature(...)]` is used when cfg `USE_RUSTC_FEATURES` is enabled. Thebuild script automatically does this when a nightly compiler is detectedor `RUSTC_BOOTSTRAP` is set.Signed-off-by: Gary Guo Link: https://github.com/Rust-for-Linux/pin-init/commit/885c5d83d7eb778a796d4a17380a0898b0d0a571[ Added kernel build system changes to always enable USE_RUSTC_FEATURES.

Fri, 16 Jan 2026 11:54:16 +0100

rust: pin-init: remove `try_` versions of the initializer macrosThe `try_[pin_]init!` versions of the initializer macros aresuperfluous. Instead of forcing the user to always write an error in`try_[pin_]init!` and not allowing one in `[pin_]init!`, combine theminto `[pin_]init!` that defaults the error to`core::convert::Infallible`, but also allows to specify a custom one.Projects using pin-init still can provide their own defaultinginitializers using the `try_` prefix by using the `#[default_error]`attribute added in a future patch.[ Adjust the definition of the kernel's version of the `try_` initializer macros - Benno]Reviewed-by: Gary Guo Tested-by: Andreas Hindborg Signed-off-by: Benno Lossin List of files: /linux/rust/pin-init/examples/pthread_mutex.rs

Thu, 05 Jun 2025 17:52:54 +0200

rust: pin-init: examples, tests: use `ignore` instead of conditionally compiling testsChange `#[cfg(cond)]` to `#[cfg_attr(not(cond), ignore)]` on tests.Ignoring tests instead of disabling them still makes them appear in thetest list, but with `ignored`. It also still compiles the code in thosecases.Some tests still need to be ignore, because they use types that are notpresent when the condition is false. For example the condition is`feature = std` and then it uses `std::thread::Thread`.Suggested-by: Alice Ryhl Link: https://lore.kernel.org/all/aDC9y829vZZBzZ2p@google.comLink: https://github.com/Rust-for-Linux/pin-init/pull/58/commits/b004dd8e64d4cbe219a4eff0d25f0a5f5bc750caReviewed-by: Christian Schrefl Link: https://lore.kernel.org/all/20250605155258.573391-1-lossin@kernel.orgSigned-off-by: Benno Lossin List of files: /linux/rust/pin-init/examples/pthread_mutex.rs

rust: pin-init: examples, tests: add conditional compilation in order to compile under any feature combinationIn the CI, all examples & tests should be run under all featurecombinations. Currently several examples & tests use `std` withoutconditionally enabling it. Thus make them all compile under any featurecombination by conditionally disabling the code that uses e.g. `std`.Link: https://github.com/Rust-for-Linux/pin-init/pull/50/commits/fdfb70efddbc711b4543c850ee38a2f5a8d17cb6Link: https://lore.kernel.org/all/20250523125424.192843-2-lossin@kernel.orgSigned-off-by: Benno Lossin List of files: /linux/rust/pin-init/examples/pthread_mutex.rs
