TL;DR — The Linux Kernel Mentorship Program is hosted on the LFX platform and provides a structured path to become a Linux kernel contributor. Full-time (12-week) and part-time (24-week) tracks available. This is one of the most technically challenging — and rewarding — open-source programs.
What is the Linux Kernel Mentorship Program?
The Linux Kernel Mentorship Program (LKMP) helps developers become long-term contributors to the Linux kernel — the core of every Android phone, every cloud server, and most of the internet’s infrastructure. This program is run through the LFX Mentorship platform but focuses specifically on kernel development. You’ll work with experienced kernel developers on real patches that get merged into the mainline Linux kernel.Why It’s Special
- You contribute to the Linux kernel — the most impactful open-source project in history
- Direct mentorship from kernel maintainers — people who have been contributing for decades
- Your patches go into production — used by billions of devices worldwide
- Career differentiator — kernel experience is rare and highly valued by employers (Google, Red Hat, Intel, Meta all hire kernel developers)
Eligibility
Same as general LFX Mentorship:- 18+ years old
- Eligible to work in your country
- Not a current maintainer of the subsystem you’re applying to
- Basic C programming knowledge and willingness to learn kernel development
Tracks
| Track | Duration | Time Commitment |
|---|---|---|
| Full-time | 12 weeks | ~40 hours/week |
| Part-time | 24 weeks | ~20 hours/week |
What You’ll Work On
Typical kernel mentorship projects include:- Bug fixes — Finding and fixing bugs in kernel subsystems
- Code cleanup — Improving code quality, removing deprecated APIs
- New features — Implementing functionality in drivers, filesystems, networking
- Testing — Writing kernel tests, improving test coverage
- Documentation — Improving kernel documentation (yes, it needs help)
- Device drivers
- Filesystem code
- Networking stack
- Memory management
- Security modules
How to Prepare
Linux kernel development has a steep learning curve. Here’s how to prepare:Prerequisites
- Strong C programming — The kernel is written almost entirely in C
- Linux command line — Comfortable navigating, compiling, and debugging from terminal
- Git proficiency — Kernel uses git with specific email-based workflow (
git send-email) - Basic OS concepts — Processes, memory management, file systems, interrupts
Recommended Preparation Steps
Set up a kernel development environment
Install a Linux distro (Ubuntu/Fedora), clone the kernel source, and learn to build it from source.
Read 'Linux Kernel Development' by Robert Love
The standard introductory book for kernel development.
Complete the kernel newbies tutorials
kernelnewbies.org has excellent guides for first-time contributors.
Submit your first patch
Even a small coding style fix counts. Follow the kernel’s patch submission process using
git send-email.Stipend
