The Linux Kernel Mentorship Program (LKMP) wiki page on required contributions describes stable-release testing and kernel debugging as the central work, while documentation conversion and selected kernel tasks are marked optional. However, that page was last modified on and says updates were in progress. Treat its counts and six-week schedule as historical guidance, and confirm the rules for the active LKMP session before relying on them.
What the LKMP page treats as core contribution work
The guidance focuses on participating in the kernel release process and investigating real bugs. It explicitly says, “Please note that quality of patches is what will add value, not the quantity.” Its example contrasts ten whitespace-only patches with fewer, more substantial patches; that is qualitative advice, not a published statistic.
The source is the Linux Foundation Wiki’s Linux Kernel Mentorship Program Required Contributions page. Because the page is dated and its current-session status is not established, use the activities below as what that page described rather than as confirmed 2026 admission requirements.
Stable-release participation
The stable-release exercise is intended to show how fixes move from mainline into stable kernels and how maintainers manage that process.

Activities listed by the page
- Subscribe to the stable-kernel release mailing list.
- Assist stable-release maintainers.
- During the page’s stated six-week application process, boot-test at least three stable kernel releases and report the results.
The “at least three” releases and six-week period belong to the page’s 2021 guidance. They should not be presented as a verified requirement for a current cohort without confirmation from the active LKMP listing or organizers.
Debugging exercise
The debugging work is framed as self-study in diagnosing boot failures, crashes and driver problems. The page asks applicants to work through Syzbot reports and document what they learn.
What to do for each report
- Find two or three Syzbot reports involving a null-pointer dereference or a
WARNand containing a reproducer. - Run the reproducer and determine whether the problem can be reproduced in your environment.
- Inspect the crash report and relevant source code to develop a possible cause.
- Write a short report for each bug and share it with Shuah Khan and the
linux-kernel-menteesmailing list.
The page points learners toward kernel-debugging techniques such as git bisect, selecting useful debug configuration options, dynamic debugging and examining source history. A useful report should distinguish an observed reproduction from an explanation that remains a hypothesis.
Optional contribution tracks
The wiki page labels the following work optional, so it should not be confused with the stable-release and debugging activities it presents as the main contribution areas.

Staging-tree style cleanup
The page suggests running checkpatch.pl against a file in a staging driver, then correcting the reported style problems. It presents this as practice for learning the kernel patch workflow, not as a substitute for a substantive contribution.
Sparse static analysis
Another practice task is to enable Sparse through the kernel Makefile, inspect the resulting diagnostics and fix errors where appropriate. This is likewise described as a way to gain experience with the process.
Quick Recap
How to interpret the contribution guidance
- Prioritize evidence of useful work: a reproducible investigation, clear report or meaningful patch is more valuable than a large patch count.
- Separate required-looking work from optional work: the page’s stable-release and debugging sections are central; documentation conversion and kernel-task selection are explicitly optional on that page.
- Keep the date attached to every number: three releases, six weeks, two or three Syzbot reports, two documentation files and two kernel tasks all come from the page last modified January 20, 2021.
- Verify the active cohort’s rules: the page says updates were in progress, and its current applicability has not been established.
