NAME
       generic_unplug_device - fire a request queue

SYNOPSIS
       void generic_unplug_device(struct request_queue * q);

ARGUMENTS
       q
	   The struct request_queue in question

DESCRIPTION
       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, the request_fn defined for the queue is invoked and
       transfers started.
