With __packed__ (which is preferrably written as __packed) the data is not aligned to u64 as the comment says. Aligning u64's is a good thing, so (for example) pad the space after type (I don't think we need more than u16 here). david -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
