Allows you to augment the callers keyset with your own.

允许您使用自己的键集来扩充调用者的键集。

However, a Level 1 driver can support dynasets if it supports extended fetch and keyset-driven cursors.

但是只要1级驱动程序支持扩展的获取和键集驱动游标，它就可以支持动态集。

A kernel keyset is a representation of a collection of kernel keys and the desired read or write access to them.

内核键集是内核键集合，以及对它们进行读写所需的权限的表示形式。

The kernel's use of keys is likely to evolve over time, which could make your keyset insufficient in the future.

键在内核中的使用很可能会随着时间的推移而发生变化，这可能使得您的键集无法满足将来的需求。
