H A Dgfs2-glocks.rst25 DLM 等操作。若某线程获取此锁，则在释放时必须调用
34 排他（EX）。它们对应以下 DLM 锁模式：
37 Glock 模式 DLM 锁模式
39 UN IV/NL 未加锁（无关联的 DLM 锁）或 NL
73 go_callback 若 DLM 发送回调以释放此锁时调用
145 1. DLM 锁时间（非阻塞请求）
146 2. DLM 锁时间（阻塞请求）
147 3. 请求间隔时间（指向 DLM）
149 非阻塞请求指无论目标 DLM 锁处于何种状态均能立即完成的请求。
156 2. glock 代码顶层的持有者排队数（通常远大于 DLM 锁请求数）
