blk_sync_queue(9)
NAME
blk_sync_queue - cancel any pending callbacks on a queue
SYNOPSIS
void blk_sync_queue(struct request_queue * q);
ARGUMENTS
- q
- the queue
DESCRIPTION
The block layer may perform asynchronous callback activity on a queue,
such as calling the unplug function after a timeout. A block device may
call blk_sync_queue to ensure that any such activity is cancelled, thus
allowing it to release resources that the callbacks might use. The
caller must already have made sure that its ->make_request_fn will not
re-add plugging prior to calling this function.
