METHOD AND APPARATUS FOR SCHEDULING BLOCK DEVICE INPUT/OUTPUT REQUESTS

摘要

A method and apparatus for scheduling block device input/output requests, which fall within the field of computer memories. The method comprises: generating a block device input/output request firstly, wherein the block device input/output request comprises a write operation request (101); then judging whether the generated block device input/output request can be combined with block device input/output requests in a request queue (102); and if not, sending the generated block device input/output request to a foremost position of the request queue when a destination device of the generated block device input/output request is a solid state disk or an SD card (103a). By means of the method and device for scheduling the block device input/output requests, the efficiency of write operation is improved.
