 Contains disk I/O functions, which are called by the file system operations. For instance, if the file system needs to read a specific sector from the disk, it calls disk_read. Disk operations are queued as requests to the sddf queue between the file system and the block device (blk virt), where worker threads may block until responses are received.

 During execution, the file system function may initiate one or more disk operations, such as reading or writing data. These operations are enqueued as block read/write requests in the queue between the file system and the block subsystem (blk virtualizer).

 The operation is completed, and the result is sent back to the client via the response queue.
