Linux Kernel: 9P Hardening and VFS Hang Fix
Filesystem reliability dominates with a large 9P cleanup and new transports, plus a core VFS fix for an infinite loop in dentry name handling. Static analysis also gains three new Coccinelle checks.

Hello, today is Wednesday, November fourth, twenty twenty-six, and this is your Linux Kernel briefing.
The big signal is filesystem robustness, with a broad hardening push to the Nine P network filesystem and a core virtual filesystem fix for a hang during name lookups.
First theme: Nine P cleanup. Merge seven d one four seven one e pulls a large late-cycle batch described as mostly automated, language-model-driven fixes. For developers, that means tighter validation and edge-case handling: rejecting error replies with no error code, treating zero-length reads as end of file,…
Second, a core virtual filesystem hang is fixed in commit five one six two eight six one. The dentry name snapshot helper could loop forever if a dentry was freed during an overlay F S read-copy-update walk. It replaces a temporary try variant that could fail spuriously during renames with a single helper keyed on…
Third, static checking gets smarter. Merge zero five four four one d six adds three Coccinelle semantic patches to catch misuse of the cleanup attribute for automatic freeing, to promote typed device-managed allocation helpers, and to encourage the array end macro.
What's next: test Nine P mounts…
