Good morning, it's Sunday, November 8th, 2026, and this is Linux Kernel Daily.
The signal across nine merges is defensive validation: stop trusting on-disk structures, network input, and timing before acting on them.
First, filesystems and file sharing. The Btrfs merge fixes a race where deleting a subvolume by number could remove the wrong one if it was renamed mid-call, plus three scrub races that risked use-after-free, lost errors, or a hang on cancel. It also restores file attribute changes on compressed files without…
Second, graphics and audio stabilization for the 7.4 cycle. Weekly graphics fixes are led by AMD graphics, covering reset, virtual memory, backlight, power and display output, with Intel fixes for broken tiled 5K displays and power-saving glitches, plus scheduler and shared-memory corrections. The sound pull closes…
Finally, bus and power correctness. SPI now waits to confirm a device before requesting its interrupt, and fixes zero-length memory lists that caused hard failures on 64K-page systems. SCSI fixes a target reference leak, and regulator fixes voltage selection and avoids a sleeping lock in a fast interrupt path.
What's next: test large-cluster NTFS…
