What's missing here is the context. Maybe this is the appropriate tone to talk to this particular person, and he wouldn't get the message otherwise. Having spent years in management I've discovered that with some people a mere hint would be enough to course correct, and with others you need to use direct, unvarnished language to get them to understand things. I never used quite as direct language as this, but I can imagine people and situations which might call for it. Although even then, I'd do it strictly in private. This is the kind of thing that people who have never managed other people find very hard to understand or appreciate. I'm also thankful that Linus gets severely upset by things that may degrade Linux IO performance, rather than just kick back, relax, and allow it to be merged.
