blk_start_queueing — initiate dispatch of requests to device
void blk_start_queueing ( | struct request_queue * | q) ; |
This is basically a helper to remove the need to know whether a queue
is plugged or not if someone just wants to initiate dispatch of requests
for this queue. Should be used to start queueing on a device outside
of ->request_fn
context. Also see blk_run_queue
.
The queue lock must be held with interrupts disabled.
