As an embedded software developer that does linux kernel drivers I've come to love the tab size 8 indentation level.

I'm paraphrasing: "if your indentation level gets too deep, it's time to rethink/refactor your function."

And with tab 8 you'll notice it rather quick if your function does too much/unrelated stuff.

A function should be short and do one thing only, if possible. It also makes unit testing easier if that's a requirement.
