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. |
