Announcing the release of Linux Kernel 4.3 (Mainline), Linus Torvalds wrote:
“Linux Kernel 4.3 brings network update and a late fix for a x86 vm86 mode bug introduced by the vm86 cleanups, but other than that it’s just a collection of various small oneliners all over. Ok, the vm86 mode thing was a one-liner too, it was just slightly more nerve-wracking because it looked scarier than it was before people (Andy) figured out what was going on.”
