By the time you pick this, these commits will have been in linux-next for quite a while. No conflicts expected. No changes to the C side. Please pull for v6.3 -- thanks!

The major ones being: - Sync: new types 'Arc', 'ArcBorrow' and 'UniqueArc'. - Types: new trait 'ForeignOwnable' and new type 'ScopeGuard'. There is also a substantial removal in terms of lines: - 'alloc' crate: remove the 'borrow' module (type 'Cow' and trait 'ToOwned'). ---------------------------------------------------------------- Boqun Feng (1): rust: MAINTAINERS: Add the zulip link Finn Behrens (1): rust: prelude: prevent doc inline of external imports Gary Guo (1): rust: compiler_builtins: make stubs non-global Maíra Canal (1): rust: delete rust-project.json when running make clean Miguel Ojeda (1): rust: alloc: remove the `borrow` module (`ToOwned`, `Cow`) Wedson Almeida Filho (12): rust: sync: add `Arc` for ref-counted allocations rust: sync: allow type of `self` to be `Arc` or variants rust: sync: allow coercion from `Arc` to `Arc` rust: sync: introduce `ArcBorrow` rust: sync: allow type of `self` to be `ArcBorrow` rust: sync: introduce `UniqueArc` rust: sync: add support for dispatching on Arc and ArcBorrow. rust: types: introduce `ScopeGuard` rust: types: introduce `ForeignOwnable` rust: types: implement `ForeignOwnable` for `Box` rust: types: implement `ForeignOwnable` for the unit type rust: types: implement `ForeignOwnable` for `Arc` MAINTAINERS | 1 + Makefile | 2 +- rust/Makefile | 15 ++ rust/alloc/borrow.rs | 498 -------------------------------------- rust/alloc/lib.rs | 3 +- rust/alloc/vec/mod.rs | 3 + rust/bindings/bindings_helper.h | 1 + rust/bindings/lib.rs | 1 + rust/compiler_builtins.rs | 5 +- rust/helpers.c | 19 ++ rust/kernel/lib.rs | 6 + rust/kernel/prelude.rs | 8 +- rust/kernel/sync.rs | 10 + rust/kernel/sync/arc.rs | 524 ++++++++++++++++++++++++++++++++++++++++ rust/kernel/types.rs | 215 ++++++++++++++++- 15 files changed, 808 insertions(+), 503 deletions(-) delete mode 100644 rust/alloc/borrow.rs create mode 100644 rust/kernel/sync.rs create mode 100644 rust/kernel/sync/arc.rs
