[GIT PULL] pin-init changes for v7.2-rc1

[Gary Guo]

Hi Miguel,

There is more developments this cycle than the last one, with a mix of
improvements and cleanups. No breaking changes to users expected.

Tuple structs did not make it this cycle, I hope it'll finally land the next
one. I have also been working on getting pin-init to support self-referential
types, which I plan to send next cycle (although unsure it can land in the next
one).

The refactoring commits have been in linux-next for a while. There a few
patches taken later in the cycle, and they have all been in linux-next since
2026-06-01. Feel free to wait for a few more rounds before pulling if you see
fit.

Best,
Gary

  rust: pin_init: internal: use `loop {}` to produce never value (2026-05-29 21:58:36 +0100)

----------------------------------------------------------------
pin-init changes for v7.2

User visible changes:

- `non_snake_case` warnings will no longer be generated 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
  nova tree next cycle.

- Non-cfg attributes are now properly filtered out in derived structs. This
  improves pin-init compatibility with other derive macros.

- Projection types have their where clause properly inserted now.

Other changes:

- MSRV is bumped to 1.82 and associated cleanups.

- There is an overhaul on how init slots are projected. The new approach is
  easier to justify with safety comments.

- More functions are marked as inline, which should help mitigate super-long
  symbol name issue due to lack of inlining.

- Various small code quality cleanups.
