.SH "DESCRIPTION"
.PP
Linux uses plugging to build bigger requests queues before letting
the device have at them. If a queue is plugged, the I/O scheduler
is still adding and merging requests on the queue. Once the queue
gets unplugged (either by manually calling this function, or by
calling \fBblk_run_queues\fR), the request_fn defined for the
queue is invoked and transfers started.
