I guess I'm giving upstream reviewers a bit of a nasty reputation by
frequently stating that this or that stuff won't be accepted. They're
not a bunch of cynical bastards who enjoy putting others down.
But there are a lot of issues one has to pay attention to in such a big
shared project that would never be considered relevant in isolated
To give just one example, hardly anybody ever writes a new driver
completely from scratch. We all look at other code that has similar
functionality or that uses the same parts of the infrastructure. This
means that anything we put into the kernel today can become somebody
else's example tomorrow, and it is to everybody's benefit if this
example doesn't lead people astray.
Most of the time, it's us who are looking for guidance (*), and we
wouldn't like the examples we use to be confusing or full of hidden
