FLEXIBLE OVER-PROVISIONING OF STORAGE SPACE WITHIN SOLID-STATE STORAGE DEVICES (SSDs)

At least one non-transitory computer readable storage medium configured to store instructions that, when executed by at least one processor included in a computing device, cause the computing device to implement a file system that establishes over-provisioned storage space within a solid-state storage device (SSD), by carrying out steps that include:

• receiving a first request to create a file, wherein the first request includes a size for the file;
• establishing the file within the file system by:
• identifying at least one extent that corresponds to storage space within the SSD that satisfies the size for the file, and
• associating the file with the at least one extent to indicate that the storage space is occupied;
• receiving a second request to cause (i) the file to remain established within the file system, and (ii) the storage space to be marked free within the SSD;
• and
• for the at least one extent:
• issuing, to the SSD, a third request that causes the storage space to be marked free within the SSD.

A computing device configured to over-provision storage space within a solid-state storage device (SSD), the computing device comprising:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the computing device to implement a file system configured to:
• receive a first request to create a file, wherein the first request includes a size for the file;
• establish the file within the file system by:
• identifying at least one extent that corresponds to storage space within the SSD that satisfies the size for the file, and
• associating the file with the at least one extent to indicate that the storage space is occupied;
• receive a second request to cause (i) the file to remain established within the file system, and (ii) the storage space to be marked free within the SSD;
• and
• for the at least one extent:
• issue, to the SSD, a third request that causes the storage space to be marked free within the SSD.
