Abstract
In accordance with one or more aspects, one or more portions of at least one file that have been freed are determined. One or more delete notifications are generated that identify the one or more portions of the at least one file. Each portion is identified as a range of data on a storage device, and each delete notification includes one or more ranges of data on the storage device. A determination is made as to when to send the generated delete notifications based on one or more threshold-based criteria. These generated delete notifications are then sent to a storage stack.
