Typedef Documentation

typedef struct spa_config_dirent spa_config_dirent_t

typedef struct spa_config_lock spa_config_lock_t

typedef struct spa_error_entry spa_error_entry_t

typedef struct spa_history_phys spa_history_phys_t

typedef enum spa_proc_state spa_proc_state_t

State machine for the zpool-pooname process.

The states transitions are done as follows:

	From		To			Routine
	PROC_NONE	-> PROC_CREATED		spa_activate()
	PROC_CREATED	-> PROC_ACTIVE		spa_thread()
	PROC_ACTIVE	-> PROC_DEACTIVATE	spa_deactivate()
	PROC_DEACTIVATE	-> PROC_GONE		spa_thread()
	PROC_GONE	-> PROC_NONE		spa_deactivate()

Enumeration Type Documentation

enum spa_proc_state

State machine for the zpool-pooname process.

The states transitions are done as follows:

	From		To			Routine
	PROC_NONE	-> PROC_CREATED		spa_activate()
	PROC_CREATED	-> PROC_ACTIVE		spa_thread()
	PROC_ACTIVE	-> PROC_DEACTIVATE	spa_deactivate()
	PROC_DEACTIVATE	-> PROC_GONE		spa_thread()
	PROC_GONE	-> PROC_NONE		spa_deactivate()
   

Enumerator:

SPA_PROC_NONE	spa_proc = &p0, no process created
SPA_PROC_CREATED	spa_activate() has proc, is waiting
SPA_PROC_ACTIVE	taskqs created, spa_proc set
SPA_PROC_DEACTIVATE	spa_deactivate() requests process exit
SPA_PROC_GONE	spa_thread() is exiting, spa_proc = &p0

Enumerator:

ZIO_TASKQ_ISSUE
ZIO_TASKQ_ISSUE_HIGH
ZIO_TASKQ_INTERRUPT
ZIO_TASKQ_INTERRUPT_HIGH
ZIO_TASKQ_TYPES
