This is a problem. Can some light be shed on why only 1 patch of the 2 got applied? This could lead to big problems, which seems to be the case for this one in fact. A Depends-on could be used here, but it's pretty hard for a submitter to do that, as the sha isn't known before it goes into the maintainers tree. -- Jens Axboe
