Now that Linux 6.1-rc1 was released, here is my look at all of the interesting kernel changes and new features that landed over the past two weeks. Linux 6.1 is shaping up to be another exciting kernel with many new software features, new hardware enablement work, and other changes for this end-of-year 2022 kernel version that is also likely to be the next Linux LTS release.

Among the key highlights for Linux 6.1 are the initial Rust infrastructure has been merged, MGLRU, various new AMD CPU features from adding the Platform Management Framework (PMF) to new perf features, faster file sharing between Linux hosts and guest VMs using 9P, the Kernel Memory Sanitizer (KMSAN) was merged, warning by default over W+X mappings, preparations for WiFi 7 and 802.11be on the networking side, new open-source GPU driver work, and much more.

Beyond all the exciting feature changes, Linux 6.1 is also notable in likely being the Linux 2022 LTS kernel release to be supported for the long-term.
