NTFS AND MEMORY HOTFIXES LAND AHEAD OF 7.1 FINAL

The kernel is closing rc5 with critical fixes for filesystem corruption, uninitialized memory leaks, and power profile detection on USB-C laptops.

Three major fix sets hit the tree in the last 24 hours. The NTFS subsystem merged four patches [1] addressing index depth validation, security descriptor memory leaks, and volume label state corruption, the kind of silent data corruption that ships to production undetected. Simultaneously, Andrew Morton's MM hotfixes [2] pulled 14 patches including nine memory-related fixes marked stable and two critical memory-hotplug corrections from Muchun Song. On the userspace side, omarchy fixed a race condition [5] where udev power_supply events fire before sysfs updates on Lenovo Yoga Pro 7 systems, leaving performance mode locked after USB-C unplug. The ATA subsystem [3] corrected deferred command handling to prevent incorrect workqueue usage in PATA drivers, and ksmbd server [4] closed three null pointer dereferences and a memory leak in ACL parsing. Build tooling saw a pacman versioning fix [6] to allow smooth rc-to-stable upgrades without triggering downgrades, and archinstall refactored logging internals [8] for maintainability. Docker multi-arch support lands in omarchy [7] by default, eliminating arm64 build friction.

Action items

→ Pull latest -rc5 if you maintain NTFS or memory-heavy workloads torvalds/linux [immediate]
→ If shipping on Lenovo USB-C, test power profile switching before 7.1 final basecamp/omarchy [plan]
→ Monitor ksmbd deployments for the null pointer fixes in ACL code paths torvalds/linux [monitor]
