It comes directly from Russell's code:
http://article.gmane.org/gmane.linux.kernel/1046606

But I do prefer to add the braces. Your proposed patch is ok, although
I prefer to have the important code at the end of the function, and
the error check before that.

Anyway, Russell has come with a different approach, so I have to try
that instead.

Cheers.
