This conversion patch for supporting 64 bit time for lutimes mostly differs from the work performed for futimes (when providing __futimes64) with adding the AT_SYMLINK_NOFOLLOW flag to utimensat. It also supports passing file name instead of file descriptor number, but this is not relevant for utimensat used to implement it. All the design and conversion decisions are exactly the same as for futimens conversion.
