o:lustre# lfs find --stripe-count +10000 .
./ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff

In ll_dir_ioctl() we should at least zero out lmm_magic when the file has not stripe info.
