So rc5 is almost exactly the same size as rc4 was. I'd be happier if the rc's were shrinking, but I guess I should be thankful they at least don't seem to be growing.
There's nothing particularly worrisome going on, although I'm still trying to think about the NUMA balancing performance regression. It may not be a show-stopper, but it's annoying, and I want it fixed. We'll get it, I'm sure.
In the meantime, rc5 is mostly driver updates (all over the driver tree: gpu, usb, sound, networking, hid, input, pinctrl, etc etc) with a few arch updates (x86, arm, arm64, sparc) and some filesystem fixes (mainly btrfs). And a smattering of non-driver networking fixes too.
Shortlog appended, although it's not particularly interesting. Most of the bigger patches were reverts, which is as it should be at this stage.
