open source community

Zachary Dupont wrote a letter to his hero Linus Torvalds back in 2014. Here, they catch up on stage at Open Source Summit NA 2017.

The Linux Foundation works through our projects, training and certification programs, events and more to bring people of all backgrounds into open source. We meet a lot of people, but find the drive and enthusiasm of some of our youngest community members to be especially infectious. In the past couple of months, we’ve invited 13-year-old algorithmist and cognitive developer Tanmay Bakshi, 11-year-old hacker and cybersecurity ambassador Reuben Paul, and 15-year-old programmer Keila Banks to speak at Linux Foundation conferences.

In 2014 when he was 12, Zachary Dupont wrote a letter to his hero Linus Torvalds. We arranged for Zach to meet Linus–a visit that helped clinch his love for Linux. This year, Zach came to Open Source Summit in Los Angeles to catch up with Linus and let us know what he’s been up to. He’s kept busy with an internship at SAP and early acceptance to the Computer Networking and Digital Forensics program at the Delaware County Technical School.

The open source community encouraged Zach to pursue his passions. They’ve inspired him, and he plans to give back in the future.

We encourage everyone to find ways to bring more people of all ages into open source. Volunteer your time to teach students or people making mid-career changes how to code, spend time on writing documentation for your open source project so others can get to know it better, or simply take the time to answer beginner questions on message boards. The more people we bring into the community, the stronger we will be in the years ahead.

The 2017 Linux Kernel Report illustrates the kernel development process and highlights the work of some of the dedicated developers creating the largest collaborative project in the history of computing.

Roughly 15,600 developers from more than 1,400 companies have contributed to the Linux kernel since 2005, when the adoption of Git made detailed tracking possible, according to the 2017 Linux Kernel Development Report released at the Linux Kernel Summit in Prague.

This report — co-authored by Jonathan Corbet, Linux kernel developer and editor of, and Greg Kroah-Hartman, Linux kernel maintainer and Linux Foundation fellow — illustrates the kernel development process and highlights the work of some of the dedicated developers who are creating the largest collaborative project in the history of computing.

Jens Axboe, Linux block maintainer and software engineer at Facebook, contributes to the kernel because he enjoys the work. “It’s challenging and fun, plus there’s a personal gratification knowing that your code is running on billions of devices,” he said.

The 2017 report covers development work completed through Linux kernel 4.13, with an emphasis on releases 4.8 to 4.13. During this reporting period, an average of 8.5 changes per hour were accepted into the kernel; this is a significant increase from the 7.8 changes seen in the previous report.

Here are other highlights from the report:

  • Since the last report, more than 4,300 developers from over 500 companies have contributed to the kernel.
  • 1,670 of these developers contributed for the first time — about a third of contributors.
  • The most popular area for new developers to make their first patch is the “staging tree,” which is a place for device drivers that are not yet ready for inclusion in the kernel proper.
  • The top 10 organizations sponsoring Linux kernel development since the last report are Intel, Red Hat, Linaro, IBM, Samsung, SUSE, Google, AMD, Renesas, and Mellanox.

Kernel developer Julia Lawall, Senior Researcher at Inria, works on the Coccinelle tool that’s used to find bugs in the Linux kernel. She contributes to the kernel for many reasons, including “the potential impact, the challenge of understanding a huge code base of low-level code, and the chance to interact with a community with a very high level of technical skill.”

The Linux kernel community came close this year to setting a new record for the number of changes merged in a single release, according to the latest Linux Kernel Development report released today by The Linux Foundation.

Kernel version 4.6 saw an astounding 13,517 patches merged in 63 days — just shy of the record set by version 3.15 at 13,722 patches on June 8, 2014.

But, changes to the kernel kept up their breakneck pace over the past 15 months, with more than 3 million lines of code added to the Linux kernel at a rate of 7.8 changes per hour.

“The ability to sustain this rate of change for years is unprecedented in any previous public software project,” according to the report.

The seventh edition of this report details the developers contributing to the kernel, the companies they work for, and the most significant changes made to the code and the development process since kernel version 3.18. The data mostly covers development since the last report was released in March 2015 — versions 3.19 to 4.7 — but some statistics go back to 2005 when development moved to the Git repository, and even back to Linus Torvalds’ first release in 1991.  

Celebrating the 25th Anniversary of Linux

This year the report also reflects on 25 years of Linux kernel development as the Linux and open source community gathers at LinuxCon North America in Toronto Wednesday night for a gala celebration commemorating the day Linus Torvalds first released Linux on Aug. 25, 1991.

At almost 22 million lines of code and a new release happening every 9-10 weeks, the Linux kernel is one of the largest, fastest moving open source projects in the history of technology. It’s also one of the most important as the core of the Linux operating system, which runs most of modern technology — from Android phones and Chromebooks, to nuclear submarines, the space station, global stock exchanges, and much more.

What started as Torvalds’ passion project has evolved over the past 25 years into a collective effort to build and maintain the code by thousands of developers employed by hundreds of companies.

“Clearly, the kernel developers are doing something right,” reads the report. “This report provides an update on what those developers have been doing and why they continue to be successful.”

Here are some of the highlights from the report, compiled from Git and analyzed by LWN Editor Jon Corbet and Linux kernel maintainer and Linux Foundation Fellow Greg Kroah-Hartman. Download the full report for more in-depth data and analysis.

2015-2016 Linux Kernel Development Highlights

From the report:

  • Almost 115,000 changesets have been merged since the 3.18 release on Dec. 7, 2014.

  • Contributions came from 5,062 individual developers representing nearly 500 corporations.  

  • 2,355 of those developers were first-time contributors

  • New features include support for live patching of the kernel, support for persistent-memory devices, encrypted storage for the ext4 filesystem, numerous networking enhancements with a focus on IPv6 and data-center improvements, and much more.

  • The “zero-day build and boot robot” testing system found nearly 400 bugs (all of which were fixed).

  • The busiest development cycle was kernel 4.6 with 13,517 patches merged — just shy of the record set by version 3.15 at 13,722 patches.

The top 10 developers contributing changes to the kernel were:

Name                         Number of changes
H Hartley Sweeten            1,456
Geert Uytterhoeven           1,036
Arnd Bergmann                  877
Al Viro                        782
Takashi Iwai                   735
Lars-Peter Clausen             729
Mauro Carvalho Chehab          714
Ville Syrjälä                  707
Linus Walleij                  661
Dan Carpenter                  631

The top 10 companies, which employ kernel developers to contribute to the Linux kernel, make up nearly 57 percent of the total changes to the kernel. The category “none,” which represents volunteer developers who aren’t paid by any company, fell to the No. 3 spot this year from No. 1 in the last report issued in 2015. And Renesas moved up in the rankings from No. 13, replacing Texas Instruments at No. 10.  A large portion of development continues to be developers of unknown corporate affiliation, who typically contribute 10 or fewer changes.

Company                Changes    Percent of total
Intel                  14,384     12.9%
Red Hat                 8,987      8.0%
None                    8,571      7.7%
Unknown                 7,582      6.8%
Linaro                  4,515      4.0%
Samsung                 4,338      3.9%
SUSE                    3,619      3.2%
IBM                     2,995      2.7%
Consultants             2,938      2.6%
Renesas Electronics     2,239      2.0%
