The "write less than a full block to the end of the file" is actually
a reasonably common case.
It may not make for a great filesystem benchmark, but it also isn't
actually insane. People who do logging in user space do this all the
time, for example. And it is *not* stupid in that context. Not at all.
It's never going to be the *main* thing you do (unless you're AIM),
but I do think it's worth fixing.
And AIM7 remains one of those odd benchmarks that people use. I'm not
quite sure why, but I really do think that the normal "append smaller
chunks to the end of the file" should absolutely not be dismissed as
stupid.
