The 6.1 kernel is out

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.

Headline features in 6.1 include reworked, LLVM-based control-flow integrity, initial support for kernel development in Rust, support for destructive BPF programs, some significant io_uring performance improvements, better user-space control over transparent huge-page creation, improved memory-tiering support, fundamental memory-management rewrites in the form of the multi-generational LRU and the maple tree data structure, the kernel memory sanitizer, and much more. See the LWN merge-window summaries (part 1, part 2) and the KernelNewbies 6.1 page for more information.
