Linux 7.3 RISC-V)
With the in-development Linux 7.3 is support for discovering and enumerating support for several newer RISC-V ISA extensions. Plus there are improvements to its control flow integrity Shadow Stack handling, CPU context switch support for QoS tagging, using UEFI runtime services for restart and powering off, and other improvements.

Linux 7.3 HWMON)
Merged last week for the Linux 7.3 kernel were all the hardware monitoring (HWMON) driver updates for Linux 7.3, which included supporting several more ASUS desktop motherboards, a few AIO liquid cooling products, more Lenovo system support, and per-CCD temperature monitoring on AMD EPYC 9005 server processors.

Better Performance)
Following the main set of memory management "MM" changes submitted for Linux 7.3, Andrew Morton sent in his "non-MM" pull request of the other patches he's been collecting from various developers for this next Linux kernel release. Standing out there were some improvements to the RAID 5/6 benchmark-based algorithm selection.

EFI Indefinite Stall)
The EFI updates were merged today for the in-development Linux 7.3 kernel. Most notable with the EFI updates is now enforcing a timeout foe EFI runtime service completions rather than potentially hanging indefinitely.

Linux 7.3 DRM)
The Direct Rendering Manager (DRM) subsystem updates have been merged for the ongoing Linux 7.3 merge window. There is a lot of exciting GPU kernel driver improvements this cycle ranging from some notable enhancements to old AMD Radeon graphics hardware up through enabling support for some next-generation AMD graphics IP blocks to over on the Intel side where Nova Lake S graphics are being enabled by default.

ReactOS + Job Objects)
Merged yesterday to the ReactOS code-base is initial support for Job Objects, which is an important milestone in the road to being able to run more modern Windows software under this open-source operating system striving for Windows driver/application compatibility.

Micron FAMFS File-System)
The NVDIMM and direct access (DAX) patches have been merged for the Linux 7.3 cycle. Most of the DAX/NVDIMM activity this cycle is on making preparations for the upcoming submission of Micron's FAMFS file-system.

AMD Zen 4 / Zen 5 Tuning)
An AMD compiler engineer posted a patch on Saturday for the GNU Compiler Collection (GCC). The two-line patch adjusts the misprediction cost for Zen 4 and Zen 5 processors, which ends up yielding a 12% improvement in one SPEC CPU benchmark on Zen 5 and a 9% improvement on Zen 4.

New AES Encryption APIs)
Eric Biggers of Google continues carrying out great work on the Linux kernel crypto code. For Linux 7.3 he's landed work on new library APIs for most of the AES encryption modes used within the kernel. Moving forward this will open the door to more performance optimizations, reducing code duplication, and other enhancements.

Linux 7.3 Input)
The big set of input subsystem updates were merged earlier this week for the Linux 7.3 cycle. It's a random assortment of different improvements as well as bug/security fixes driven in part by the flow of AI/LLM generated discoveries.
The eCryptfs stacked cryptographic filesystem implementation for the Linux kernel to transparently encrypt files saw a number of bug fixes for the Linux 7.3 kernel. A number of these bug fixes deal with potential maliciously-crafted data and vulnerable going back to the 2006 introduction of eCryptfs as this option known for its use on Ubuntu home directory encryption and Chrome OS.

Redox + EEVDF)
The Rust-written, from-scratch Redox OS operating system has switched to using an EEVDF based scheduler design. In doing so they are promoting a 2.6x increase in throughput and a 782x improvement in fairness.
In early 2025 it was being discussed to potentially drop the HFS and HFS+ file-system support with the code having been orphaned over a decade and becoming a maintenance burden. But that dismal outlook quickly turned around with some developers stepping up to maintain the old Apple file-system support. Over a year later, fortunately, it's turned out to be a success story with more HFS/HFS+ file-system fixes continuing to work their way into the mainline Linux kernel.

Steve French)
There is a changing of the guard with Linux 7.3 as the maintainer of the Common Internet File System (CIFS) / SMB3 code within the Linux kernel. Longtime maintainer, principal Linux CIFS author, and current Microsoft employee Steve French has stepped down due to health reasons.

NTFS3 Vulnerability)
A reported security vulnerability for the NTFS3 driver has gone unaddressed since being reported earlier this summer. The vulnerability allows a pre-crafted NTFS image on a USB flash drive or similar to allow the user to gain root access to the running Linux system.

GFX11.7 / RDNA 4m)
In addition to AMD's Friday afternoon big code drop of all the UALink enablement patches for the Linux kernel and the AMDGPU driver, there was another big drop from AMD to end out the week... Upstreamed to the linux-firmware.git repository is all the firmware binaries needed by the open-source driver stack for initializing their forthcoming RDNA 4m "GFX 11.7" graphics.
