Good morning. It's July 17th, 2026, and this is Linux Kernel Daily.
Today's merges are almost entirely rc-cycle bug fixes, and the throughline is data integrity under edge-case conditions - filesystems and hypervisors closing gaps that only show up under real-world stress.
Start with storage. Carlos Maiolino's XFS pull, commit e22254e, brings twenty-one fixes, several catching corruption scenarios in copy-on-write handling, quota iteration, and realtime btree checking. Notably, many of these were found with help from LLM-based review - a sign that tooling is starting to catch subtle…
The second theme is state that outlives its context - stale references after a hardware or scheduling transition. The standout is Nikunj Dadhania's KVM SVM fix, commit 25f744f. When a CPU goes offline and back online, the ASID generation counter was resetting instead of incrementing, which could let two virtual…
Smaller but worth noting: Landlock fixed a TCP Fast Open bypass, and cpufreq patched two scaling issues affecting how the scheduler perceives CPU capacity.
What to remember: if you're running virtualized workloads with CPU hotplug, the SVM ASID fix closes a real isolation gap. And if you touch…
