You are wrong, on both individual level and stereotyping to a nation of people.

On the individual level, he did do the debugging and analysis, on a smaller scope. Linus was asking a bigger scope analysis and a lot of work. Some people are willing to spend time to understand and fix problem for free. Some people have better things to do and aren't willing to spend the time to do it. That's their prerogative.

On a nation level, there are Chinese who want to get things done and there are Chinese who want to understand the root causes, just as there are people in other nations/cultures who want to get things done and there are people who want to understand the root causes.

It's not an acceptable approach in kernel development.

A patch like that has zero (actually, negative) value. It simply shouldn't be accepted and regressing to the last "working", most tested version should be the option.

So, all in all, if you are not willing to do your homework well enough, it's better for everybody if you don't bother at all. It wastes both your time and the maintainers' time. Linus' time no less.

Thanks for the explanation on the individual level. Sounds reasonable.

On your second point, yes, you can say of any cultural group that there are people who do X and people who do non-X, but that doesn't proves that there are no global traits and that all cultural stereotypes exists for no reason.

But I understand your point as "you are wrong to try to attribute the behavior of an individual to a stereotype, since they can only be used at a very broad level", and I think you're probably right.
