Method and apparatus for scheduling block device input/output requests
The present invention provides a method and apparatus for scheduling block device input/output requests, which relates to 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; then judging whether the generated block device input/output request can be combined with block device input/output requests in a request queue; and if the generated block device input/output request cannot be combined with block device input/output requests in a request queue, 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. By means of the method and apparatus for scheduling the block device input/output requests, the efficiency of write operation is improved.
