Linux Kernel: VFS Reclaim and Mount Race Fixes
A large virtual filesystem fix set resolves stranded inodes that caused out-of-memory failures and mount races that left mounts unreachable. LoongArch and crypto pulls add targeted hardening with no broader pattern.

Good morning, it's Thursday, November 12th, 2026, and this is your Linux Kernel briefing.
The dominant theme is filesystem reliability, with a large virtual filesystem fix set addressing memory reclaim and mount lifetime races that could strand resources until reboot.
First, inode and directory cache lifetime. A metadata writeback marker introduced in version 7 point 3 left clean inodes off the reclaim list on several filesystems, including unjournaled extended 4 and FAT. In testing, just updating access times pinned inodes, and creating 60,000 small files in a 96 megabyte…
Second, safer splice and control paths. Pipe buffer stealing is removed entirely. FUSE and virtual console were the only users, and they now always copy as they already did on failure. The same set clamps oversized writes from the file splice path, fixes an over-report of bytes written through system control files…
Finally, architecture and crypto hardening without a broader pattern. The LoongArch pull, in merge 79 E B 667, validates checksums and device entries for ACPI I O V T tables, fixes leaks in the file-based kexec path, and addresses virtual machine, hibernation and just-in-time issues. The crypto pull,…
