I would say this is not a technical issue, but a social one. In order
to keep the netdev people happy, you are going to limit it to 80. But
i would not be too surprised if another subsystem says the code would
be more readable with 100, like the C code in our subsystem. We want
Rust to be 100 as well.

Linux can be very fragmented like this across subsystems. Its just the
way it is, and you might just have to fit in. I don't know, we will
see.
