Starting with Rust 1.88.0 (expected 2025-06-26) [1], Clippy may start
warning about paths that do not resolve in the `disallowed_macros`
configuration:
warning: `kernel::dbg` does not refer to an existing macro
--> .clippy.toml:10:5
|
10 | { path = "kernel::dbg", reason = "the `dbg!` macro is intended as a debugging tool" },
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This is a lint we requested at [2], due to the trouble debugging
the lint due to false negatives (e.g. [3]), which we use to emulate
`clippy::dbg_macro` [4]. See commit 8577c9dca7 ("rust: replace
`clippy::dbg_macro` with `disallowed_macros`") for more details.
Given the false negatives are not resolved yet, it is expected that
Clippy complains about not finding this macro.
Thus, until the false negatives are fixed (and, even then, probably we
will need to wait for the MSRV to raise enough), use the escape hatch
to allow an invalid path.

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.
