Linus Torvalds has announced the fifth release candidate for Linux kernel 6.12. The most significant updates encompass 9p reverts, enhancements to GPU and networking drivers, as well as improvements to bcachefs. Minor adjustments encompass architecture corrections, additional filesystems, various drivers, as well as core networking and BPF enhancements.

Linux kernel 6.12-rc5 released

So rc4 last week was larger than I was hoping for, but I (optimistically) blamed just fluctuations due to random timing of pull requests since the previous week had been small.

And that does indeed seem to be the case.

Because rc5 looks perfectly normal, and maybe even on the small side of normal. The diffstat looks nice and flat too, with the exception of the removal of the da8xx fbdev driver due to it having been replaced by the tilcdc driver. And I'm sure we're all thinking the same thing: "What lovely descriptive driver names we have".

Some of the biggest changes seem to be some 9p reverts, although we do have all the usual suspects too: gpu and networking drivers, and bcachefs fixes.

But hey, there's a smattering of smaller fixes all over, the shortlog below gives some flavor of it all: arch fixes (arm64 kvm, x86, loongarch), other filesystems (xfs, btrfs, nfsd), various drivers (sound, x86 platform drivers, fbdev), and core networking and bpf.
