Linux Kernel: Stabilization Fixes for I/O, Arm64 and Filesystems
A quiet merge window focused on stabilization for the 7.4 series, with fixes for lifecycle races in NVMe, io_uring and Xen backends, hardware correctness on Arm64 and AMD IOMMU, and data integrity across XFS, Overlayfs and legacy filesystems.

Hello, it's Saturday, November 7th, 2026, and this is your Linux Kernel briefing.
The lead pattern is stabilization, not features. Across Arm, block, I-O uring, Xen and filesystems, the work targets crashes, hangs and silent corruption from lifecycle races and interrupted context.
First, the I-O path. The block pull tightens NVMe and NVMe-target handling of reconnects, disconnects and teardown, including use-after-free on failed connect, locking around forced reconnects, bounds on configuration writes, and limiting connections accepted per work run so a connect flood can't block port removal.…
Second, hardware correctness. On Arm64, event handlers for the software delegated exception interface could take nested exceptions while kernel page-table isolation trampoline vectors were still installed, looping forever and clobbering exception registers. That merge also preserves a thread register across CPU…
Finally, filesystems. The XFS fixes stabilize network file layout commit, treating it like file sync and clamping ranges to file size. Overlayfs fixes a self-deadlock with notification listeners, copy-up stale data on file-handle decode, and casefold handling. Legacy filesystem work…
