Hi,

I am recently study the dbpf code in pvfs2-1.4.0 release.
In dbpf-bstream.c, there is a function definition:

static int dbpf_bstream_read_list(TROVE_coll_id coll_id,
                                  TROVE_handle handle,
                                  char **mem_offset_array,
                                  TROVE_size *mem_size_array,
                                  int mem_count,
                                  TROVE_offset *stream_offset_array,
                                  TROVE_size *stream_size_array,
                                  int stream_count,
                                  TROVE_size *out_size_p,
                                  TROVE_ds_flags flags,
                                  TROVE_vtag_s *vtag,
                                  void *user_ptr,
                                  TROVE_context_id context_id,
                                  TROVE_op_id *out_op_id_p)

My question is, in its parameter list, does the mem_count and
stream_count must match with each other?  If yes, why should we keep
both of them?

Thanks!

Peng
