Reviewed-by: Peter Xu <pet...@redhat.com> But note that we should have this patch either squashed into previous patch, or at least it should appear earlier than patch 2 since otherwise patch 2 could possibly break. I would prefer squashing since it's really part of patch 2, and please feel free to pick my r-b if you want to resent with a squashed version in the future. Regards, -- Peter Xu
