Actually, right now the comment is correct and the name is misleading.
But I have a patch that will make the comment incorrect (and will be
fixed) and the name correct.

But since seq_has_overflowed() is to be used throughout the kernel, I
didn't want to have to go do patches all over again for a temporary
misnomer.

In other words, I'm going to change the function to really return only
if it did overflow and not just be full. But that's another patch set
to come.

I can update the change log and comment to state what will happen in
the future.

Thanks,

-- Steve
