Merge tag 'rust-6.10' of https://github.com/Rust-for-Linux/linux
Pull Rust updates from Miguel Ojeda: "The most notable change is the drop of the 'alloc' in-tree fork. This is nicely reflected in the diffstat as a ~10k lines drop. In turn, this makes the version upgrades way simpler and smaller in the future, e.g. the latest one in commit 56f64b370612 ("rust: upgrade to Rust 1.78.0"). More importantly, this increases the chances that a newer compiler version just works, which in turn means supporting several compiler versions is easier now. Thus we will look into finally setting a minimum version in the near future. Toolchain and infrastructure: - Upgrade to Rust 1.78.0 This time around, due to how the kernel and Rust schedules have aligned, there are two upgrades in fact. These allow us to remove one more unstable feature ('offset_of') from the list, among other improvements - Drop 'alloc' in-tree fork of the standard library crate, which means all the unstable features used by 'alloc' (~30 language ones, ~60 library ones) are not a concern anymore - Support DWARFv5 via the '-Zdwarf-version' flag - Support zlib and zstd debuginfo compression via the '-Zdebuginfo-compression' flag 'kernel' crate: - Support allocation flags ('GFP_*'), particularly in 'Box' (via 'BoxExt'), 'Vec' (via 'VecExt'), 'Arc' and 'UniqueArc', as well as in the 'init' module APIs - Remove usage of the 'allocator_api' unstable feature - Remove 'try_' prefix in allocation APIs' names - Add 'VecExt' (an extension trait) to be able to drop the 'alloc' fork - Add the '{make,to}_{upper,lower}case()' methods to 'CStr'/'CString' - Add the 'as_ptr' method to 'ThisModule' - Add the 'from_raw' method to 'ArcBorrow' - Add the 'into_unique_or_drop' method to 'Arc' - Display column number in the 'dbg!' macro output by applying the equivalent change done to the standard library one - Migrate 'Work' to '#[pin_data]' thanks to the changes in the 'macros' crate, which allows to remove an unsafe call in its 'new' associated function - Prevent namespacing issues when using the '[try_][pin_]init!' macros by changing the generated name of guard variables - Make the 'get' method in 'Opaque' const - Implement the 'Default' trait for 'LockClassKey' - Remove unneeded 'kernel::prelude' imports from doctests - Remove redundant imports 'macros' crate: - Add 'decl_generics' to 'parse_generics()' to support default values, and use that to allow them in '#[pin_data]' Helpers: - Trivial English grammar fix Documentation: - Add section on Rust Kselftests to the 'Testing' document - Expand the 'Abstractions vs. bindings' section of the 'General Information' document" * tag 'rust-6.10' of https://github.com/Rust-for-Linux/linux: (31 commits) rust: alloc: fix dangling pointer in VecExt<T>::reserve() rust: upgrade to Rust 1.78.0 rust: kernel: remove redundant imports rust: sync: implement `Default` for `LockClassKey` docs: rust: extend abstraction and binding documentation docs: rust: Add instructions for the Rust kselftest rust: remove unneeded `kernel::prelude` imports from doctests rust: update `dbg!()` to format column number rust: helpers: Fix grammar in comment rust: init: change the generated name of guard variables rust: sync: add `Arc::into_unique_or_drop` rust: sync: add `ArcBorrow::from_raw` rust: types: Make Opaque::get const rust: kernel: remove usage of `allocator_api` unstable feature rust: init: update `init` module to take allocation flags rust: sync: update `Arc` and `UniqueArc` to take allocation flags rust: alloc: update `VecExt` to take allocation flags rust: alloc: introduce the `BoxExt` trait rust: alloc: introduce allocation flags rust: alloc: remove our fork of the `alloc` crate ...
