It's July 29th, 2026, and this is Linux Kernel Daily.
Today's activity is all late-cycle stabilization work heading into release candidates, and the clear signal is btrfs. Ten fixes landed in commit 3-b-5-f-4-b-8, and most of them cluster around two fragile areas: zoned mode and raid56 scrub.
On zoned storage, David Sterba's pull brought fixes for a deadlock between metadata writeback and transaction commit, a missing chunk metadata reservation, and a write pointer reset issue tied to zone resets. These are the kind of bugs that surface under real workloads on zoned devices, and a deadlock in particular…
Two smaller but notable commits round things out. Kees Cook's hardening pull, in 6-0-9-f-0-3-6, fixes a naming mismatch left over from renaming STACKLEAK ERASING to K-STACK ERASE in test tooling, plus a seccomp self-test build error and a disabled compiler warning in fortify tests. These are maintainability fixes —…
What to remember: if you're running btrfs on zoned storage or relying on raid56 scrub for integrity checks, these fixes matter for your next kernel bump. Expect these to ship as part of the current release candidate cycle.
That's the briefing for July 29th. Stay patched.
