We currently have a fork of the crate with changes to `Vec`; other changes have been upstreamed (to the Rust project). This series removes the fork and exposes all the functionality as extension traits. Additionally, it also introduces allocation flag parameters to all functions that may result in allocations (e.g., `Box::new`, `Arc::new`, `Vec::push`, etc.) without the `try_` prefix -- the names are available because we build `alloc` with `no_global_oom_handling`. Lastly, the series also removes our reliance on the `allocator_api` unstable feature. Long term, we still want to make such functionality available in upstream Rust, but this allows us to make progress now and reduces our maintainance burden. In summary: 1. Removes `alloc` fork 2. Removes use of `allocator_api` unstable feature 3. Introduces flags (e.g., GFP_KERNEL, GFP_ATOMIC) when allocating Wedson Almeida Filho (10): rust: kernel: move `allocator` module under `alloc` rust: alloc: introduce the `VecExt` trait kbuild: use the upstream `alloc` crate rust: alloc: remove our fork of the `alloc` crate rust: alloc: introduce allocation flags rust: alloc: introduce the `BoxExt` trait rust: alloc: update `VecExt` to take allocation flags rust: sync: update `Arc` and `UniqueArc` to take allocation flags rust: init: update `init` module to take allocation flags rust: kernel: remove usage of `allocator_api` unstable feature rust/Makefile | 16 +- rust/alloc/README.md | 36 - rust/alloc/alloc.rs | 452 ---- rust/alloc/boxed.rs | 2463 ----------------- rust/alloc/collections/mod.rs | 160 -- rust/alloc/lib.rs | 288 -- rust/alloc/raw_vec.rs | 611 ----- rust/alloc/slice.rs | 890 ------- rust/alloc/vec/drain.rs | 255 -- rust/alloc/vec/extract_if.rs | 115 - rust/alloc/vec/into_iter.rs | 454 ---- rust/alloc/vec/is_zero.rs | 204 -- rust/alloc/vec/mod.rs | 3683 -------------------------- rust/alloc/vec/partial_eq.rs | 49 - rust/alloc/vec/set_len_on_drop.rs | 35 - rust/alloc/vec/spec_extend.rs | 119 - rust/bindings/bindings_helper.h | 3 + rust/kernel/alloc.rs | 68 + rust/kernel/{ => alloc}/allocator.rs | 6 +- rust/kernel/alloc/boxext.rs | 60 + rust/kernel/alloc/vecext.rs | 120 + rust/kernel/error.rs | 13 +- rust/kernel/init.rs | 57 +- rust/kernel/lib.rs | 5 +- rust/kernel/prelude.rs | 2 + rust/kernel/str.rs | 6 +- rust/kernel/sync/arc.rs | 44 +- rust/kernel/sync/condvar.rs | 2 +- rust/kernel/sync/lock/mutex.rs | 2 +- rust/kernel/sync/lock/spinlock.rs | 2 +- rust/kernel/types.rs | 4 +- rust/kernel/workqueue.rs | 14 +- samples/rust/rust_minimal.rs | 6 +- samples/rust/rust_print.rs | 4 +- scripts/generate_rust_analyzer.py | 2 +- 35 files changed, 340 insertions(+), 9910 deletions(-) delete mode 100644 rust/alloc/README.md delete mode 100644 rust/alloc/alloc.rs delete mode 100644 rust/alloc/boxed.rs delete mode 100644 rust/alloc/collections/mod.rs delete mode 100644 rust/alloc/lib.rs delete mode 100644 rust/alloc/raw_vec.rs delete mode 100644 rust/alloc/slice.rs delete mode 100644 rust/alloc/vec/drain.rs delete mode 100644 rust/alloc/vec/extract_if.rs delete mode 100644 rust/alloc/vec/into_iter.rs delete mode 100644 rust/alloc/vec/is_zero.rs delete mode 100644 rust/alloc/vec/mod.rs delete mode 100644 rust/alloc/vec/partial_eq.rs delete mode 100644 rust/alloc/vec/set_len_on_drop.rs delete mode 100644 rust/alloc/vec/spec_extend.rs create mode 100644 rust/kernel/alloc.rs rename rust/kernel/{ => alloc}/allocator.rs (96%) create mode 100644 rust/kernel/alloc/boxext.rs create mode 100644 rust/kernel/alloc/vecext.rs base-commit: 768409cff6cc89fe1194da880537a09857b6e4db -- 2.34.1
