Good day, and welcome to Linux Kernel Daily for August 12, 2026.
Today's activity is narrow but worth flagging: a single merge from Masami Hiramatsu's probes tree, landing right at release candidate 7 of the 7.2 cycle.
The fix, commit f5bbbfe, addresses a bug in the add-remove-uprobe self-test. The test was using the ELF entry point address directly as a file offset when registering a uprobe. That works fine for position-independent executables, but on non-PIE binaries, the virtual address can exceed the actual file size, causing…
This is test infrastructure, not core kernel logic, but it matters for anyone relying on the ftrace self-test suite to validate uprobe behavior. A false failure in continuous integration or pre-release validation can mask real problems or waste time chasing a phantom bug. Fixing it now, at rc7, is exactly the kind…
The broader theme here is release discipline. Rc7 merges are typically fixes only, and this one fits that pattern precisely, no new features, no risky refactors, just correctness in test tooling.
What's next: expect the 7.2 final release to follow shortly, with this uprobe test fix included so downstream distributions and testers get accurate…
