The headline is a major virtual filesystem fix for mount handling, landing as part of a quiet late release candidate focused on teardown bugs and device quirks.
First theme: mounts. The virtual filesystem pull reworks what happens when an unmounted mount stays connected to its parent to keep its mount point covered. That design could create reference cycles that were never freed — a loop device on the same temporary filesystem is enough to leak the loop, the filesystem and…
Second theme: safe removal. Across subsystems, drivers mishandled device or mount teardown. Memory stick now waits for request completion before freeing a card and completes requests after eject instead of dropping them. Several M M C host drivers now clean up slot devices, timeout work and power management on…
Finally, a stability sweep. Sound brings a dozen device-specific quirks and codec fixes, power domains fixes probe errors on Rockchip and serializes power changes on I M X, plus narrow fixes for direct memory access bounce handling, file integrity verification lifetime, ARM 64 trap configuration and coverage…
What's next: watch for a follow-up P C I fix for MacBook Pro…
