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/

modules-6.17-rc3.fixes Modules fixes for 6.17-rc3 (2025-08-24) tar.gz
modules-6.17-rc1 This is a small set of changes for modules, primarily to extend module users to use the module data structures in combination with the already no-op stub module functions, even when support for modules is disabled in the kernel configuration. This change follows the kernel's coding style for conditional compilation and allows kunit code to drop all CONFIG_MODULES ifdefs, which is also part of the changes. This should allow others part of the kernel to do the same cleanup. (2025-08-03) tar.gz
