coding-style.rst shows that:
        if (condition) {
                do_this();
                do_that();
        } else {
                otherwise();
        }

So git grep told me there're at least 28 similar "issues" in 
drivers/virito. And there will be a lot in the other part of the kernel

I think it's not worth to bother. We can start to work on something that 
is really interesting.

E.g we had the plan to convert to use iov iterator instead of using a 
vringh specific iov "iterator" implementation. Do you want to do that?

Thanks
