generic_unplug_devic(9)
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.
