Place definitions and implementations (incl. macro invocations) of the `Zeroable` trait first in the relevant section of `src/lib.rs`, followed by the ZeroableOption trait and its implementations. Rename `impl_non_zero_int_zeroable_option` to `impl_zeroable_option` for consistency. This commit should not introduce any functional changes. Signed-off-by: Mohamad Alsadhan <mo@sdhn.cc>
Improve impl_zeroable_option macro to handle generic impls for types like `&T`, `&mut T`, `NonNull<T>`, and others (for which `Option<T>` is guaranteed to be zeroable) with similar approach to `impl_zeroable`. Also, update old declarations to use generics e.g. `NonZeroU8` to `NonZero<u8>`. Signed-off-by: Mohamad Alsadhan <mo@sdhn.cc>
Minimal testing including: - add `tests/zeroing.rs` coverage that `zeroed::<Option<T>>()` is `None` for refs, `NonNull`, and nonzero ints. - add generic compile-check coverage for `T: ZeroableOption` (`&u8`, `&mut u8`, `NonNull<u8>`, `NonZeroU8`). - add UI compile-fail test `zeroable/option_string_not_zeroable.rs` to verify `Option<String>` is not `Zeroable`. Not entirely sure how useful these tests are but it's on a different commit so feel free to not include them. Signed-off-by: Mohamad Alsadhan <mo@sdhn.cc>

This series collects all upstream developments of pin-init to date and synchronize them to the kernel tree. A major change in this cycle is the bump of MSRV to 1.82 to get rid of unstable features, following the kernel version bump in 7.1. The MSRV is bumped straight to 1.85 as pin-init can also be used outside kernel, so we avoid bumping unless there is a need for new version. Here are the list of merged changes included in the series: - examples: mark as `#[inline]` all `From::from()`s for `Error` Rust-for-Linux/pin-init#126 - bump minimum Rust version to 1.82 Rust-for-Linux/pin-init#129 - cleanup `Zeroable` and `ZeroableOptions` Rust-for-Linux/pin-init#118 - internal: add missing where clause to projection types Rust-for-Linux/pin-init#121 - internal: internal: remove redundant `#[pin]` filtering Rust-for-Linux/pin-init#131 For information, here are the list of upstream-only changes, which are related to Cargo or tests/CI changes only. - build.rs: use `option_env!` to register env variable dependency Rust-for-Linux/pin-init#128 - clean up dependencies Rust-for-Linux/pin-init#130 - tests: add test for check correct macro hygiene Rust-for-Linux/pin-init#133 - ci: use tagged release of actions Rust-for-Linux/pin-init#134 - ci: have a single job to gate all required jobs Rust-for-Linux/pin-init#138 Best, Gary --- b4-submit-tracking --- # This section is used internally by b4 prep for tracking purposes. { "series": { "revision": 1, "change-id": "20260414-pin-init-sync-ae407945a726", "prefixes": [], "presubject": "" } }
