Yes, I hear that a lot, so you need to follow up with, "why does it matter what version Greg picks?", and then their response to me always is, "so we know what kernel to start to rebase our huge patchsets to earlier", which again, is the thing we want to keep them from doing! I got a few emails when I stopped 3.14.y this week along the lines of, "oops, we were using that kernel, what are we supposed to do now!" Each time I asked if 4.4 or 4.8 worked for them. And each time I got back a response a day later along the lines of, "oh wow, yes, it does, we'll use that." I have half-a-mind to just skip a LTS kernel for a whole year and see if anyone even notices, I feel it is being used for all the wrong reasons... thanks, greg k-h
