Linux Kernel: Release Candidate Cleanup Across the Board
This is a classic late-rc merge window — seven pull requests, all fixes, spanning file systems, virtualization, power management, and security, with no new features. The common thread is hardening existing code ahead of release rather than adding capability.

This is Linux Kernel, your daily briefing, for July 17, 2026.
Today's activity is all cleanup, no new ground. Seven merges landed, every one of them a fixes pull for the upcoming release candidate, touching file systems, virtualization, and power management. The pattern here isn't any single big feature — it's the kernel entering stabilization mode.
Start with file systems, where three separate subsystems needed correctness fixes. The SMB client, commit F-C-E-2-D-F-A, fixed fallocate behavior — flushing dirty data before punching holes and refreshing allocation size after duplicate extents. Small bugs, but the kind that can silently corrupt data if left alone.…
Second theme is virtualization reliability. The KVM pull, commit C-two-seven-zero-A-four-two, is the largest single batch — forty-eight commits across ARM 64, s390, and x86. Notable ones include a fix for ASID collisions after CPU hotplug on AMD systems, a null pointer fix in exception tracing, and a rejection of…
Third theme is power and security correctness. Landlock, in commit four-eight-one-E-D-5-D, fixed a TCP Fast Open bypass — a real security gap in the sandboxing feature. And two separate power management pulls, P-M…
