Linux Kernel Daily: The Great Regression Cleanup
Ahead of the 7.3 release, Linus pulled a dense wave of fixes across memory management, tracing, scheduling, and timers, with several addressing long-standing or subtle data-integrity bugs. The common thread is release hardening: correctness and use-after-free fixes converging right before a stable cut.

It's September 14th, 2026, and this is Linux Kernel Daily.
The signal today is release hardening. With 7.3 approaching, a cluster of merges landed that all share one goal: closing correctness gaps before they ship, some of them years old.
Start with memory management. Commit 704340f merges x86 fixes including one for user-space data loss with MADV_FREE and transparent huge pages — a bug Dave Hansen notes has likely existed for a couple of years, just waiting for the right combination of reclaim pressure and THP usage to surface. Alongside it, several…
Tracing saw the largest single pull, commit 2209876, bundling twenty-five fixes from Steven Rostedt's tree. Two patterns stand out: use-after-free bugs — in trigger cleanup, in histogram registration, in options-file handling during instance teardown — and accounting errors in the newer ring-buffer remotes feature.…
Scheduler and timer fixes round this out. The EEVDF scheduler got two rb-tree accounting fixes for slice and augmentation values, and proxy scheduling now correctly attributes cgroup CPU time to the execution context rather than the scheduling context — a distinction that matters for accounting accuracy under proxy…
Rounding…
