These are queues that have a wait free side where an NHRT can request to read or write some data (depending on the class) without the danger of blocking.

这些类是具有无等待端的队列，在这里，一个NHRT可以请求读或写某些数据(具体取决于类)，而不存在阻塞的风险。

Since this wait queue is used sparsely, a smaller wait queue implementation using hash queues to find the correct wait queue has been implemented in the rmap patch.

因为这个等待队列极少用到，所以在 rmap 补丁中实现了一个更小的队列，通过哈希队列来找到正确的等待队列。
