Things remain fairly calm for 4.12, although not quite as calm as it appeared earlier in the week. I think two thirds of the commits came in on Friday or the weekend..
But timing aside, it all looks fairly normal. It's all pretty small, nothing really stands out as unusual. Pretty much exactly the "standard distribution of patches", with two thirds being drivers (GPU and rdma, but also scsi target, hid, input, md, scsi..) and the rest being a mix of arch (mainly x86 this time around), filesystems (overlayfs and misc) and other core code (mm and headers).
