DESCRIPTION

16       Linux uses plugging to build bigger requests queues before letting the
17       device have at them. If a queue is plugged, the I/O scheduler is still
18       adding and merging requests on the queue. Once the queue gets
19       unplugged, the request_fn defined for the queue is invoked and
20       transfers started.
