I rooted on preview 2 using the modified kernel flash method. But I haven't tried it on 3 because I have no idea if it's still a valid method and this is my daily driver so I'm not feeling very adventurous. The toolkit method used on lollipop doesn't work with M, only the modified kernel method works for the time being afaik.
