`#[pin_data]` failed to propagate the struct's `where` clause to the generated projection struct. As a result, bounds written in a `where` clause could be dropped during expansion, causing type errors when fields depended on those bounds. Fix this by adding the missing `where` clause to the generated projection struct.

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": "" } }
