摘要： A delete notification can be received at a storage stack filter in a storage stack. It can be determined whether the delete notification applies to an entire storage device. If the delete notification does not apply to the entire storage device, a first set of actions can be taken with the storage stack filter in response to the delete notification. If the delete notification does apply to the entire storage device, a second set of actions can be taken with the storage stack filter in response to the delete notification.
摘要翻译： 可以在存储堆栈中的存储堆栈过滤器处接收删除通知。 可以确定删除通知是否适用于整个存储设备。 如果删除通知不适用于整个存储设备，则响应于删除通知，可以与存储堆栈过滤器进行第一组动作。 如果删除通知适用于整个存储设备，则响应于删除通知，可以与存储堆栈过滤器进行第二组动作。

摘要： A storage stack delete notification can be received at a storage stack filter. The delete notification can indicate deletion of primary data in a primary storage region. Secondary data that is taking up storage resources managed by the storage stack filter can be identified. The secondary data can be associated with the primary storage region, and the storage resources can be resources other than the primary storage region. It can be determined whether it is useful to have the secondary data continue taking up the storage resources. If having the secondary data continue taking up the storage resources is not useful, then the storage resources can be freed.
摘要翻译： 可以在存储堆栈过滤器处接收存储堆栈删除通知。 删除通知可以指示删除主存储区域中的主数据。 可以识别占用存储堆栈过滤器管理的存储资源的次要数据。 辅助数据可以与主存储区域相关联，并且存储资源可以是除主存储区域之外的资源。 可以确定辅助数据是否继续占用存储资源是否有用。 如果继续占用存储资源的次要数据是没有用的，则可以释放存储资源。

摘要： A filter between a filesystem and a storage device in a storage stack can be configured to modify a delete notification, such as by modifying an existing delete notification or creating a new delete notification. A storage stack filter can receive an existing delete notification and determine a modified range of deleted data in response to receiving the existing notification, where a modified delete notification indicates the modified range of deleted data. A new delete notification can be created with a storage stack filter positioned below a filesystem in a storage stack, where the new delete notification indicates a range of deleted data. The new or modified delete notification can be passed down the storage stack.
