Hello, today is Saturday, November 7th, 2026, and this is Linux Kernel Daily.
The big signal is stabilization, not features. Across Arm, I O M M U, block, async I O, and filesystems, the work converges on teardown races, use-after-free, overflows, and stale state that only show up under suspend, reset, or heavy reconnects.
Start with privileged hardware paths. The Arm sixty-four fixes, pulled in merge d four eight seven, address nested faults in the software delegated exception interface. With kernel page table isolation, an event interrupting user space could leave trampoline vectors installed and loop forever, while also clobbering…
Second, storage and async I O under stress. The block pull centers on N V Me and its target. Fixes cover use-after-free on failed connect, null controller handling on reconnect, target R D M A disconnect ordering, bounding accepted connections so a connect flood cannot block port removal, and authentication handling…
Finally, filesystems. X F S stabilizes parallel N F S layout commit, clamping ranges, holding invalidation locks, and aligning sync behavior with file data sync. Overlay F S fixes a self-deadlock when a permission listener reads…
If you run…
