    I did indeed write that.

    Tabs are 8 characters in the kernel coding style.

    And yes, I also wrote the other quote:

    and I think that's in many ways even more important than the 8-character
    tab, because deep indentation is unreadable even if you *can* fit it on a
    single line.

    In the kernel, we try to split functions up, and perhaps use inline
    functions etc, and really really avoid deep indentation.
