Use of delete notifications by file systems and applications to release storage space

摘要

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.

1. A computing device comprising:
at least a memory and a processor configured to utilize instructions in the memory to cause the computing device to:
determine that one or more portions of at least one file have been freed;generate one or more delete notifications identifying the one or more portions of the at least one file, each portion being identified as a range of data on a storage device, and each delete notification including one or more ranges of data on the storage device;determine when the generated one or more delete notifications are to be sent to a storage stack based on one or more threshold-based criteria, the one or more threshold-based criteria including a frequency with which read and/or write requests are being sent to the storage stack; andsend the generated one or more delete notifications to the storage stack.
