Neat to see zero-copy networking get TX, after RX shipped a while ago. Good stuff. I wonder how it overlaps-with/interacts with the various kernel offloads? I forget if this is TCP only or UDP too: would be really nice with QUIC / HTTP3 to see more love for UDP. https://www.phoronix.com/news/Device-Memory-TCP-TX-Linux-6.1...

The filesystem Folio work has been yielding such amazing results. In general I'm just so impressed how much the storage subsystems keep improving! IO_Uring has totally changed the game in terms of iops delivered just on it's own. But then the various filesystems & upper level multi-queue support have also been consistently finding really nice wins. Folios have been incredible! https://lwn.net/Articles/1015320/

EROFS added compressed metadata support, which is showing a 2.5X win for readdir(3) (reading files from a directory). Given it's use in awesome works like composefs for next-gen & content-addressed based container overlay type systems, this is a nice win. https://github.com/composefs/composefs

Probably my favorite new feature is AMDGPU user queue (userq) work. Rather than the driver having to build out all the future work, now userspace can directly build the work of stuff to be done, sprinkling in various fences and what not. Some very interesting potential for GPGPU & perhaps ML! https://www.phoronix.com/news/Mesa-25.2-High-Priority-USERQ https://www.phoronix.com/news/Linux-6.16-AMDGPU-User-Queues

The Kernel Newbies release log is one of my favorite things to read through. It wasn't bursting-at-the-seams with awesome as you sometimes get with releases, but 6.16 was still very fun. https://news.ycombinator.com/item?id=44717122 https://kernelnewbies.org/Linux_6.16
