Linux 6.1 Released With MGLRU, Initial Rust Code

Linus Torvalds just released Linux 6.1 as stable!

Linux 6.1 integrates the exciting Multi-Gen LRU (MGLRU) overhaul of the page reclamation code, the initial Rust programming language support though still being built up, the new AMD Platform Management Framework, a variety of open-source graphics driver improvements, Btrfs performance optimizations, the Kernel Memory Sanitizer, introduction of the Maple Tree data structure, and a lot of other hardware driver work. See my Linux 6.1 feature overview for a more extensive list at all of the prominent kernel changes this round.

Now onward to the very exciting Linux 6.2 merge window.

Linus Torvalds wrote in today's v6.1 release announcement:

So here we are, a week late, but last week was nice and slow, and I'm much happier about the state of 6.1 than I was a couple of weeks ago when things didn't seem to be slowing down.

Of course, that means that now we have the merge window from hell, just before the holidays, with me having some pre-holiday travel coming up too. So while delaying things for a week was the right thing to do, it does make the timing for the 6.2 merge window awkward.
