Merge tag 'pin-init-v7.2' of https://github.com/Rust-for-Linux/linux into rust-next

Pull pin-init updates from Gary Guo:
 "User visible changes:

   - Do not generate 'non_snake_case' warnings for identifiers that are
     syntactically just users of a field name. This would allow all
     '#[allow(non_snake_case)]' in nova-core to be removed, which I will
     send to the nova tree next cycle.

   - Filter non-cfg attributes out properly in derived structs. This
     improves pin-init compatibility with other derive macros.

   - Insert projection types' where clause properly.

  Other changes:

   - Bump MSRV to 1.82, plus associated cleanups.

   - Overhaul how init slots are projected. The new approach is easier
     to justify with safety comments.

   - Mark more functions as inline, which should help mitigate the
     super-long symbol name issue due to lack of inlining.

   - Various small code quality cleanups."
