Combining data block i/o and checksum block i/o into a single i/o operation during processing by a storage stack

A system, comprising:

• a storage device communicatively coupled to a storage stack comprising a file system layer;
• and
• an underlying storage device layer managing physical storage blocks of the storage device, wherein the underlying device layer:
• receives an intermediary I/O operation targeting a range of blocks including a first block and a second block requested by the file system layer;
• executes one or more I/O operations to access the first block and the second block and exclude intermediary blocks between the first block and the second block;
• constructs a single intermediary response I/O operation based upon execution of the one or more I/O operations;
• and
• transmits the single intermediary response I/O operation to the file system layer as a single response for both the first block and the second block targeted by the intermediary I/O operation.

A non-transitory machine readable medium comprising instructions, which when executed by a machine, causes the machine to perform operations comprising:

• receiving a request to access a first block and a second block stored within a storage device managed by an underlying storage device layer;
• constructing a single intermediary I/O operation targeting a range of blocks including the first block and the second block;
• and
• accessing, utilizing the single intermediary I/O operation, the first block and the second block from the storage device.
