Merge tag 'sched_ext-for-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext

Pull sched_ext updates from Tejun Heo:

- cgroup sub-scheduler groundwork

Multiple BPF schedulers can be attached to cgroups and the dispatch
path is made hierarchical. This involves substantial restructuring of
the core dispatch, bypass, watchdog, and dump paths to be
per-scheduler, along with new infrastructure for scheduler ownership
enforcement, lifecycle management, and cgroup subtree iteration

The enqueue path is not yet updated and will follow in a later cycle

- scx_bpf_dsq_reenq() generalized to support any DSQ including remote
local DSQs and user DSQs

Built on top of this, SCX_ENQ_IMMED guarantees that tasks dispatched
to local DSQs either run immediately or get reenqueued back through
ops.enqueue(), giving schedulers tighter control over queueing
latency

Also useful for opportunistic CPU sharing across sub-schedulers

- ops.dequeue() was only invoked when the core knew a task was in BPF
data structures, missing scheduling property change events and
skipping callbacks for non-local DSQ dispatches from ops.select_cpu()

Fixed to guarantee exactly one ops.dequeue() call when a task leaves
BPF scheduler custody

- Kfunc access validation moved from runtime to BPF verifier time,
removing runtime mask enforcement

- Idle SMT sibling prioritization in the idle CPU selection path

- Documentation, selftest, and tooling updates. Misc bug fixes and
cleanups

Merge tag 'rust-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux

Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:

- Bump the minimum Rust version to 1.85.0 (and 'bindgen' to 0.71.1).

As proposed in LPC 2025 and the Maintainers Summit [1], we are
going to follow Debian Stable's Rust versions as our minimum
versions.

Debian Trixie was released on 2025-08-09 with a Rust 1.85.0 and
'bindgen' 0.71.1 toolchain, which is a fair amount of time for e.g.
kernel developers to upgrade.

Other major distributions support a Rust version that is high
enough as well, including:

+ Arch Linux.
+ Fedora Linux.
+ Gentoo Linux.
+ Nix.
+ openSUSE Slowroll and openSUSE Tumbleweed.
+ Ubuntu 25.10 and 26.04 LTS. In addition, 24.04 LTS using
their versioned packages.

The merged patch series comes with the associated cleanups and
simplifications treewide that can be performed thanks to both
bumps, as well as documentation updates.

In addition, start using 'bindgen''s '--with-attribute-custom-enum'
feature to set the 'cfi_encoding' attribute for the 'lru_status'
enum used in Binder.

Link: https://lwn.net/Articles/1050174/ [1]

- Add experimental Kconfig option ('CONFIG_RUST_INLINE_HELPERS') that
inlines C helpers into Rust.

Essentially, it performs a step similar to LTO, but just for the
helpers, i.e. very local and fast.

It relies on 'llvm-link' and its '--internalize' flag, and requires
a compatible LLVM between Clang and 'rustc' (i.e. same major
version, 'CONFIG_RUSTC_CLANG_LLVM_COMPATIBLE'). It is only enabled
for two architectures for now.

The result is a measurable speedup in different workloads that
different users have tested. For instance, for the null block
driver, it amounts to a 2%.

- Support global per-version flags.

While we already have per-version flags in many places, we didn't
have a place to set global ones that depend on the compiler
version, i.e. in 'rust_common_flags', which sometimes is needed to
e.g. tweak the lints set per version.

Use that to allow the 'clippy::precedence' lint for Rust < 1.86.0,
since it had a change in behavior.

- Support overriding the crate name and apply it to Rust Binder,
which wanted the module to be called 'rust_binder'.

- Add the remaining '__rust_helper' annotations (started in the
previous cycle).

'kernel' crate:

- Introduce the 'const_assert!' macro: a more powerful version of
'static_assert!' that can refer to generics inside functions or
implementation bodies, e.g.:

fn f<const N: usize>() {
const_assert!(N > 1);
}

fn g<T>() {
const_assert!(size_of::<T>() > 0, "T cannot be ZST");
}

In addition, reorganize our set of build-time assertion macros
('{build,const,static_assert}!') to live in the 'build_assert'
module.

Finally, improve the docs as well to clarify how these are
different from one another and how to pick the right one to use,
and their equivalence (if any) to the existing C ones for extra
clarity.

- 'sizes' module: add 'SizeConstants' trait.

This gives us typed 'SZ_*' constants (avoiding casts) for use in
device address spaces where the address width depends on the
hardware (e.g. 32-bit MMIO windows, 64-bit GPU framebuffers, etc.),
e.g.:

let gpu_heap = 14 * u64::SZ_1M;
let mmio_window = u32::SZ_16M;

- 'clk' module: implement 'Send' and 'Sync' for 'Clk' and thus
simplify the users in Tyr and PWM.

- 'ptr' module: add 'const_align_up'.

- 'str' module: improve the documentation of the 'c_str!' macro to
explain that one should only use it for non-literal cases (for the
other case we instead use C string literals, e.g. 'c"abc"').

- Disallow the use of 'CStr::{as_ptr,from_ptr}' and clean one such
use in the 'task' module.

- 'sync' module: finish the move of 'ARef' and 'AlwaysRefCounted'
outside of the 'types' module, i.e. update the last remaining
instances and finally remove the re-exports.

- 'error' module: clarify that 'from_err_ptr' can return 'Ok(NULL)',
including runtime-tested examples.

The intention is to hopefully prevent UB that assumes the result of
the function is not 'NULL' if successful. This originated from a
case of UB I noticed in 'regulator' that created a 'NonNull' on it.

Timekeeping:

- Expand the example section in the 'HrTimer' documentation.

- Mark the 'ClockSource' trait as unsafe to ensure valid values for
'ktime_get()'.

- Add 'Delta::from_nanos()'.

'pin-init' crate:

- Replace the 'Zeroable' impls for 'Option<NonZero*>' with impls of
'ZeroableOption' for 'NonZero*'.

- Improve feature gate handling for unstable features.

- Declutter the documentation of implementations of 'Zeroable' for
tuples.

- Replace uses of 'addr_of[_mut]!' with '&raw [mut]'.

rust-analyzer:

- Add type annotations to 'generate_rust_analyzer.py'.

- Add support for scripts written in Rust ('generate_rust_target.rs',
'rustdoc_test_builder.rs', 'rustdoc_test_gen.rs').

- Refactor 'generate_rust_analyzer.py' to explicitly identify host
and target crates, improve readability, and reduce duplication.

And some other fixes, cleanups and improvements"

Merge patch series "rust: bump minimum Rust and `bindgen` versions"

As proposed in the past in e.g. LPC 2025 and the Maintainers Summit [1],
we are going to follow Debian Stable's Rust versions as our minimum
supported version.

Debian Trixie was released with a Rust 1.85.0 toolchain [2], which it
still uses to this day [3] (i.e. no update to Rust 1.85.1).

Debian Trixie was released with `bindgen` 0.71.1, which it also still
uses to this day [4].

Debian Trixie's release happened on 2025-08-09 [5], which means that a
fair amount of time has passed since its release for kernel developers
to upgrade.

Thus bump the minimum to the new versions, i.e.

- Rust: 1.78.0 -> 1.85.0
- bindgen: 0.65.1 -> 0.71.1

There are a few main parts to the series, in this order:

- A few cleanups that can be performed before the bumps.
- The Rust bump (and its cleanups).
- The `bindgen` bump (and its cleanups).
- Documentation updates.
- The `cfi_encoding` patch, added here, which needs the bump.
- The per-version flags support and a Clippy cleanup on top.

rust: remove `RUSTC_HAS_COERCE_POINTEE` and simplify code

With the Rust version bump in place, the `RUSTC_HAS_COERCE_POINTEE`
Kconfig (automatic) option is always true.

Thus remove the option and simplify the code.

In particular, this includes removing our use of the predecessor unstable
features we used with Rust < 1.84.0 (`coerce_unsized`, `dispatch_from_dyn`
and `unsize`).

With the Rust version bump in place, the `RUSTC_HAS_SLICE_AS_FLATTENED`
Kconfig (automatic) option is always true.

Thus remove the option and simplify the code.

In particular, this includes removing the `slice` module which contained
the temporary slice helpers, i.e. the `AsFlattened` extension trait and
its `impl`s.

rust: simplify `RUSTC_VERSION` Kconfig conditions

With the Rust version bump in place, several Kconfig conditions based on
`RUSTC_VERSION` are always true.

Thus simplify them.

The minimum supported major LLVM version by our new Rust minimum version
is now LLVM 18, instead of LLVM 16. However, there are no possible
cleanups for `RUSTC_LLVM_VERSION`.
