Initially, virtual memory of an application is assigned to a first portion of memory. The application may issue a read request to an external device. The external device is instructed to record any response to the read request in the first portion of memory. The read request may be cancelled as follows. The virtual memory of the application may be re-assigned to a second portion of the memory. If and when the external device finishes processing the read request, the external device's response to the read request may still be saved in the first portion of memory, even though the read request has been cancelled. Such action of the external device would ordinarily corrupt the virtual memory of the application, but due to the memory re-assignment, no corruption of the virtual memory occurs. Similar techniques may be applied to cancel write requests."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and systems for I/O cancellation","description":"Described herein are techniques for cancelling I/O requests.
