I have grown to dislike debatable parts of checkpatch over the years,
which probably colors my reaction to things like this.

I'd prefer for checkpatch to check things that are fairly black-and-white.

Ok,. fair enough. That makes it more likely to work.

That said, I did a grep for six tabs, and we do seem to have quite a
bit of code like that. 67 _thousand_ lines just in C files, if I did
my grep right.

And many of them seem reasonable. Quite a lot of them seem to be to
just line things up with the previous line. Although some really are
due to excessively deep indentation. But it doesn't seem exactly
black-and-white to me.
