Linus Torvalds c84d574698 Merge tag 'modules-6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/modules/linux
Pull module updates from Daniel Gomez:
 "Rust module parameter support:

   - Add Rust module parameter support, enabling Rust kernel modules to
     declare and use module parameters. The rust_minimal sample module
     demonstrates this, and the rust null block driver will be the first
     to use it in the next cycle. This also adds the Rust module files
     under the modules subsystem as agreed between the Rust and modules
     maintainers.

  Hardening:

   - Add compile-time check for embedded NUL characters in MODULE_*()
     macros. This module metadata was once used (and maybe still) to
     bypass license enforcement (LWN article from 2003):

   - Add Aaron Tomlin as reviewer for the Modules subsystem"

Linux kernel
============

The Linux kernel is the core of any Linux operating system. It manages hardware,
system resources, and provides the fundamental services for all other software.

Quick Start
-----------

* Report a bug: See Documentation/admin-guide/reporting-issues.rst
* Get the latest kernel: https://kernel.org
* Build the kernel: See Documentation/admin-guide/quickly-build-trimmed-linux.rst
* Join the community: https://lore.kernel.org/

Essential Documentation
-----------------------

All users should be familiar with:

* Building requirements: Documentation/process/changes.rst
* Code of Conduct: Documentation/process/code-of-conduct.rst
* License: See COPYING

Documentation can be built with make htmldocs or viewed online at:
https://www.kernel.org/doc/html/latest/
