For the Rust 1.87.0 release, Clippy was expected to warn with:
error: use `core::ptr::eq` when comparing raw pointers
--> rust/kernel/list.rs:438:12
|
438 | if self.first == item {
| ^^^^^^^^^^^^^^^^^^ help: try: `core::ptr::eq(self.first, item)`
|
= help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#ptr_eq
= note: `-D clippy::ptr-eq` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(clippy::ptr_eq)]`
However, a backport to relax a bit the `clippy::ptr_eq` finally landed,
and thus Clippy did not warn by the time the release happened.
Thus remove the `allow`s added back then, which were added just in case
the backport did not land in time.
See commit a39f308709 ("rust: allow Rust 1.87.0's `clippy::ptr_eq`
lint") for details.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
