Linux Kernel Daily: The RC3 Fix Wave
This is a classic release-candidate stabilization day: hwmon, watchdog, networking, power management, and CIFS trees all landed batches of fixes for use-after-free bugs, reference leaks, and locking races ahead of 7.3. The common thread is defensive hardening against memory safety and lifecycle bugs across drivers and subsystems.

Good morning. It's September 11th, and this is Linux Kernel Daily.
Today's pull requests share one clear signal: the run-up to 7.3 is dominated by memory safety and reference-counting fixes, not new features. Nearly every subsystem pull today is patching a use-after-free, a reference leak, or a race condition introduced by earlier work.
Start with hwmon, merged by Guenter Roeck in commit a-a-four-one-six-five-nine. Twenty-four fixes, and the pattern is locking discipline: a potential use-after-free in pec_store, a workqueue leak in applesmc on register failure, a use-after-free in gpio-fan's alarm work, and missing locks in the sht4x driver.…
CIFS tells the same story at a higher stakes level. Paulo Alcantara's pull, commit zero-a-nine-six-d-zero, fixes file type corruption in reparse point parsing, a heap overflow in DACL rewriting, and reference count leaks in oplock break handling that cause busy-inode crashes on unmount. There's also a DFS superblock…
Networking follows suit. Jakub Kicinski's net pull, commit seven-eight-four-four-five-zero-two, includes a Bluetooth fix for incorrect connection event length, and an ICE driver fix — commit f-c-two-six-six-a-five — removing…
