Linus Torvalds released the 7.2 kernel on August 17, after noting that the number of fixes coming in was still "bigger than I would have wished for". In fact, 7.2 was one of the busiest development cycles in the kernel's history, adding nearly 600,000 lines of code. It's time to look at some statistics to get a handle on how the kernel's development community is changing.

This year's edition of the Free and Open Source Software Yearly conference, better known as "FOSSY", moved north to the beautiful (and enormous) campus of the University of British Columbia (UBC) in Vancouver, Canada from its home for the three previous editions: Portland, Oregon, in the US. There were many different types of talks at FOSSY, from deeply technical kernel-track topics, through talks on legal and community issues, to the "FOSS in Daily Life" talks. In the "Toolchains and Other Development Tools" track, Timothy Sample gave a presentation about bootstrappable builds, which is somewhat less well-known than its cousin, reproducible builds, though LWN did look at the topic just over two years ago. In short, a bootstrappable build is one that starts with a tiny program that can build another slightly larger program, which can build yet another, and so on, until the entirety of a modern Linux user space is built from a small seed. Ultimately, it results in code with a completely understood origin—unlike a typical Linux user space today.

Version 5.0 of GNU Poke, a binary-data editor, has been released. This release includes a number of improvements to the Poke compiler, additions to the Poke language, as well as runtime and standard library updates. See below for the full list of changes.

The Software Freedom Conservancy has announced that Mark J. Wielaard has been honored with the second annual Distinguished Service Award in Software Freedom for his many years of service to software freedom.

Mark is one of many key FOSS developers who has designed his career so that his employers have funded much of his FOSS work. Nevertheless, Mark continues his volunteer work after hours as a key contributor who maintains Sourceware — the oldest FOSS collaboration and developer infrastructure hosting site in history.

In addition to his work on Sourceware, Wielaard is a member of the DWARF Debugging Standard Committee, the maintainer for Valgrind and elfutils, as well as a contributor to various other GNU projects.

The 7.2 kernel has been released. Linus said:

Well, this last week of the release was - once again - bigger than I would have wished for, but hey, with the whole "new normal" thing, if I delayed releases for that reason we'd probably never have a release at all.

Significant features in this release include common attributes support in the bpf() system call, cache-aware load balancing for the CPU scheduler, large-folio support in the Btrfs filesystem, further swap subsystem improvements, improvements to the Landlock security module, support for block devices with inline encryption hardware via the dm-inlinecrypt device-mapper target, and much more. See the LWN merge window summaries (part 1, part 2) and the KernelNewbies 7.2 page for more information.
