变更在
config/mmc-local.conf中新增了三条 UBS IO 专用配置项（第 38、40、42 行）：ubsio.disk.pathubsio.mem.size_in_gbubsio.standalone.device_count根据项目文档
doc/install_whl.md（第 117、119、131 行），UBS IO 使用独立的配置文件ubsio.conf，通过环境变量UBSIO_CONFIG_PATH指定路径。MMC 的mmc-local.conf由Configuration::LoadFromFile加载，仅解析ock.mmc.*命名空间的键（定义在mmc_config_const.h的ConfConstant中），不会识别ubsio.*键。UBS IO 库通过dlopen动态加载，其初始化函数ubsio_client_init只接受deviceId，自身内部读取ubsio.conf。后果：用户若取消注释这些配置项并写入实际值，MMC 不会将其传递给 UBS IO，配置不会生效，用户将困惑于为何设置无效。即使这些行当前处于注释状态，它们的存在也会引导用户在错误的配置文件中修改 UBS IO 参数。
建议：将三条
ubsio.*配置项及其注释从mmc-local.conf中移除，改为在config/ubsio.conf中创建（该文件目前不存在于仓库中）。同时建议ubsio.disk.path提供一个示例路径值（如/dev/nvme0n1），与其他注释掉的配置项保持一致。
