Well, you definitely need explicit timestamp conversions on the result of statx to be usable in struct stat when userspace "long" is 64-bit, for BE because otherwise the integer nanoseconds will be in the wrong place for struct timespec, and for LE if the "__reserved is held in case we need a yet finer resolution." might start being returned as nonzero (for integer attoseconds, I suppose) in future. -- Joseph S.
