It seems like these nodes have been in the Linux tree since 3.12 and 3.17, respectively and these changes break backwards-compatibility. Has anyone thought about the possible consequences? Although, looking more closely it seems like this isn't the first time that backwards-compatibility was broken in these files, so perhaps nobody cares... Thierry
