摘要：A data access request to a file system is decomposed into a plurality of lower-
level I/O tasks. A logical combination of physical storage components is represented as ahierarchical set of objects. A parent I/O task is generated from a first object in responseto the data access request. A child I/O task is generated from a second object toimplement a portion of the parent I/O task. The parent I/O task is suspended until thechild I/O task completes. The child I/O task is executed in response to an occurrence ofan event that a resource required by the child I/O task is available. The parent I/O task isresumed upon an event indicating completion of the child I/O task. Scheduling of anychild I/O task is not conditional on execution of the parent I/O task, and a state diagramregulates the child I/O tasks.
