函数名称：ldm_create_data_partitions - Create data partitions for this device*@pp: List of the partitions parsed so far*@ldb: Cache of the database structures* The database contains ALL the partitions for ALL disk groups, so we need to

函数原型：static bool ldm_create_data_partitions(struct parsed_partitions *pp, const struct ldmdb *ldb)

返回类型：bool
