Abstract
A processing system processes an I/O request and, upon interruption of the I/O request, identifies an owner of an active mount point or another entity, and then resumes processing the I/O request under the control of the identified owner. For instance, when an I/O request processed by an I/O system encounters an active mount point, the processing is interrupted as control is turned over to an active mount point driver. The active mount point driver assumes responsibility for processing the I/O request. In processing the I/O request, the active mount point driver decides what action should be taken to further processing of the I/O request. To further processing of the I/O request, the active mount point driver may utilize information from a variety of sources as well as make requests to other processes, drivers, systems, subsystems, devices, and so forth. Such actions may include those normally associated with an I/O request such as retrieving and mounting appropriate media as well as actions not normally associated with an I/O request. This technique allows arbitrary actions to be performed when grafting the name space of one device into the name space of the same or another device…
