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.
