NAME

       generic_unplug_device - fire a request queue

SYNOPSIS

       void generic_unplug_device  (request_queue_t * q);

ARGUMENTS

       q      The &request_queue_t 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.
