Linus Torvalds has announced the fourth release candidate for the upcoming Linux kernel 5.18.

Linux kernel 5.18-rc4 released

Fairly slow and calm week - which makes me just suspect that the other shoe will drop at some point.

But maybe things are just going really well this release. It's bound to happen _occasionally_, after all.

It's not only a fairly small set of commits, the diffstat is pretty small and flat too. The biggest single patch is literally killing off a zombie file that had already been deleted - well, renamed, really - once, but it didn't know to stay dead, and was resurrected by a merge mistake.

The changes are sprinkled all over, they just aren't all that big: arch updates (sound being the bulk of it, but "bulk" really is fairly misleading), some driver updates, a couple of filesystem fixes, memory management, networking, and some tooling (mainly a couple of selftests).

Scroll through the shortlog below for an overview of the changes.
