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.
