Abstract
System and method for scheduling I/O requests in a multi-tasking data processing environment. An I/O request issued by an application is placed in an I/O request holding queue. Under control of the requesting application (or, alternatively, the operating system), the I/O request is selectively canceled or moved to a service pending queue for execution. Requests can be moved either by the application or by the Operating system when an I/O completes (and hence the service pending queue has room for another IO).
