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/linked_list.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/linked_list.rs

Fri, 23 May 2025 14:54:11 +0200

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/linked_list.rs

Sat, 08 Mar 2025 12:04:18 +0100

rust: pin-init: change examples to the user-space versionReplace the examples in the documentation by the ones from theuser-space version and introduce the standalone examples from theuser-space version such as the `CMutex` type.The `CMutex` example from the pinned-init repository [1] is used inseveral documentation examples in the user-space version instead of thekernel `Mutex` type (as it's not available). In order to split offthe pin-init crate, all examples need to be free of kernel-specifictypes.Link: https://github.com/rust-for-Linux/pinned-init [1]Signed-off-by: Benno Lossin Reviewed-by: Fiona Behrens Tested-by: Andreas Hindborg Link: https://lore.kernel.org/r/20250308110339.2997091-6-benno.lossin@proton.meSigned-off-by: Miguel Ojeda List of files: /linux/rust/pin-init/examples/linked_list.rs
