This is Linux Kernel Daily for July 16th, 2026.
Today's activity is small but focused entirely on test infrastructure reliability - the tools developers depend on to trust their own testing results.
Two merges came in from Shuah Khan's kselftest tree. The first, commit e144887, fixes a pair of self-test bugs: one in the ftrace suite around reading enabled functions during module probe testing, and another in a tracing trigger test that needed to switch to using sched process exit for correctness. Neither is a…
The second merge, commit 37e2f87, is more subtle but worth remembering. It fixes warning suppression logic in bug dot c that only worked when kunit was compiled directly into the kernel. Since kunit is actually a tristate config option, meaning it can also be built as a loadable module, the old code used a plain…
The common thread here: both merges are about making sure the testing and debugging tools give developers accurate signals. If ftrace tests are misconfigured, or kunit warning suppression silently fails depending on how it's built, developers lose confidence in what their test runs are actually telling them. This is…
What's next: expect this to land cleanly in 7.2-rc4,…
