Please see the original thread about this series[1], this patch is a requirement for
two of the next patches, which does fix a few bugs with overruled error codes returned
to user space.

I was originally going to ignore these AUTOSEL mails, since the whole series was already
added to the queued more than 24 hours earlier[2]. In the queue Sasha has also added "Stable-dep-of:'.

So the weird thing is that AUTOSEL selected this patch, given that it was already in the queue.
