My preference would be to not have the v1 struct defintion but instead provide a few helpers in uuid.h that use get_unaligned_be* if needed: uuid_v1_time_low() uuid_v1_time_mid() uuid_v1_time_time_hi_and_version().. >From his previously reply it seems like Dave doesn't like that idea too much, in which case I suspect moving struct uuid_v1 back into afs and living with cast in it is the way to go. -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
