You're listening to Linux Kernel briefing for July 16th, 2026.
Today's activity is small but focused entirely on one thing: making sure the kernel's own testing tools actually work correctly.
Linus pulled two fix sets from Shuah Khan, both aimed at test infrastructure. The first, in commit e144887, addresses the kselftest suite directly. It fixes how the add-remove-fprobe-module test reads enabled functions, and it corrects the trigger-hist-poll tracing test to properly use sched process exit instead of…
The second merge, commit 37e2f87, is arguably the more interesting one. It fixes a bug in lib/bug.c where warning suppression logic was gated behind a plain sharp-ifdef check. The problem: kunit is a tristate config, meaning it can be built as a loadable module, not just built-in. The old ifdef only handled the…
The theme here is maintainability of the test harness itself. Nothing in today's activity touches core kernel subsystems, but both fixes close gaps between how tests are configured and how they actually run in practice.
What's next: these are rc4 fixes, so expect them to ride into the stable release without much friction. If you're running kunit as a module, this is worth…
