Linux Kernel: VFS Mount Rework and Driver Teardown Fixes
A large VFS pull reworks connected mounts to fix leaks, busy-check bypasses, and use-after-free paths dating back years. MMC, PCI, sound, and small architecture fixes round out late release-candidate activity.

Good morning, it's Saturday, October 10th, 2026, and this is your Linux Kernel briefing.
The big story is a deep fix to virtual file system mounts, with smaller driver teardown and hardware quirk fixes rounding out the release candidates.
First, mounts. Christian Brauner's virtual file system pull reworks so-called connected mounts to close leak cycles possible since version 4.1. A loop device on the same temporary file system as its mount point could previously leak the loop, the file system, and its contents forever when a container namespace…
Second, teardown and false alarms. The M-M-C and memory stick fixes ensure timed requests and power management are cancelled on device removal, and that ejected cards complete rather than drop requests. Separately, a P-C-I fix skips error recovery on false alarms from Advisory Non-Fatal Errors, addressing G-P-U…
Finally, steady quirks. The sound pull is a dozen device-specific fixes for U-S-B audio, H-D audio, and A-soc codecs, plus small corrections for ARM 64 trap setup, D-M-A bounce handling, file system verity freeing, and E-M-28 X-X radio unregister.
Expect a follow-up P-C-I fix next week for a MacBook power-off regression, and test…
