Oh, to have a second upvote. Literally the only two modes of interaction I’ve had with Torvalds, across multiple kernel summits, are either (1) he ignores me, maybe kind of grunting, while I’m trying to say something like “good morning” or “how are you?”, or (2) yelling at the person standing next to me, who I’m trying to collaborate with, and thus yelling at me by proxy. I hope it’s no wonder that I only hack kernel in private, for patches I need, or for close friends.
