Mike Rapoport has announced the release of the video recordings from the 2026 Linux Plumbers Conference (LPC), which was held in Prague from October 5 through October 7. Find the complete set via the YouTube playlist or look for the video links in the schedule. See also LWN's coverage of talks from LPC.

Rust has several ad-hoc mechanisms to allow user code to influence how the standard library executes. For example, custom panic handlers and custom allocators both involve registering functions that core standard library code needs to call. With more similar features planned, Jana Dönszelmann spotted the developing pattern and put together a general solution, introducing a safer, checked analogue of C's weak symbol linking. At Kangrejos 2026, she explained how this new language feature works, and proposed using it to clean up the kernel's handling of integer overflows in Rust code.

It's Sunday afternoon, and this week I somehow kept my wits together long enough to keep track of the day of the week, so the release isn't randomly delayed. Will wonders never cease?

Anyway, nothing very special seems to have happened this last week, so as expected the final 7.3 is out, and thus tomorrow the merge window for 7.4 opens. Except I'm on my annual family vacation, so instead of merging anything first thing in the morning, I'll spend most of the day on a boat and under water. I'll get back to merging in the afternoon, but I expect my schedule to be a bit unusual for a while.

This release is a record-breaker on all fronts; it brought in 18,765 non-merge commits from 3,021 developers, 807 of whom were first-time kernel developers.

Significant changes in this release include some significant binfmt_misc extensions, some group-scheduling work aimed at improving performance on large systems, the new failfs filesystem that fails all operations, the fchroot() system call, global per-CPU data for BPF programs, the completion of the sched_ext subscheduler feature, working-set tracking for virtual machines, alternative data-stream support in the ntfs3 filesystem, a long list of SMB server improvements, and much more. See the LWN merge-window summaries (part 1, part 2) and the KernelNewbies 7.3 page for details.
