Data Structures

Typedefs
typedef void(*	workqueue_func_t )(struct workqueue_task *task)
	Work queue worker function.
Functions
static void	workqueue_init (struct workqueue *queue)
	Initialize a work queue.
static void	workqueue_task_set_work_func (struct workqueue_task *task, workqueue_func_t worker_func)
	Change the worker function of a task.
static void	workqueue_task_init (struct workqueue_task *task, workqueue_func_t worker_func)
	Initialize a work queue task.
static bool	workqueue_is_empty (struct workqueue *queue)
	Check if a work queue is empty.
static bool	workqueue_task_is_queued (struct workqueue_task *task)
	Check if a work queue task has been queued.
bool	workqueue_add_task (struct workqueue *queue, struct workqueue_task *task)
	Add task to work queue.
static struct workqueue_task *	workqueue_pop_task (struct workqueue *queue)
	Remove task from front of work queue.
static void	workqueue_run_task (struct workqueue_task *task)
	Run a work queue task.
Nested Workqueues
Nested workqueues are workqueues specific to certain shared resources, for example a bus driver which can only handle one request at a time. Such drivers may create a workqueue for keeping track of tasks wanting to use the shared resource, and move them one by one into the main workqueue.
static void	nested_workqueue_init (struct nested_workqueue *wq)
	Initialize a nested workqueue.
bool	nested_workqueue_add_task (struct nested_workqueue *nwq, struct workqueue_task *task)
	Add task to nested work queue.
void	nested_workqueue_next_task (struct nested_workqueue *nwq)
	Switch to the next task in a nested work queue.
Variables
struct workqueue	main_workqueue
	The main work queue.
