void release_lockstate

(

state_owner_t *

plock_owner

)

release_lockstate: Remove every state belonging to the lock owner.

Remove every state belonging to the lock owner.

Parameters:

plock_owner

[IN] lock owner to release state for.

Definition at line 402 of file nfs4_state.c.

void release_openstate

(

state_owner_t *

popen_owner

)

release_openstate: Remove every state belonging to the open owner.

Remove every state belonging to the open owner.

Parameters:

popen_owner

[IN] open owner to release state for.

state_status_t state_add	(	cache_entry_t *	pentry,
		state_type_t	state_type,
		state_data_t *	pstate_data,

state_add: adds a new state to a file pentry

Adds a new state to a file pentry

Parameters:

pentry	[INOUT] cache entry to operate on
state_type	[IN] state to be defined
pstate_data	[IN] data related to this state
powner_input	[IN] related open_owner
pcontext	[IN] FSAL credentials
ppstate	[OUT] pointer to a pointer to the new state
pstatus	[OUT] returned status

Returns:

the same as *pstatus

Definition at line 270 of file nfs4_state.c.

state_status_t state_add_impl	(	cache_entry_t *	pentry,
		state_type_t	state_type,
		state_data_t *	pstate_data,
		state_owner_t *	powner_input,
		fsal_op_context_t *	pcontext,
		state_t **	ppstate,
		state_status_t *	pstatus
	)

state_add_impl: adds a new state to a file pentry

Adds a new state to a file pentry. This version of the function does not take the state lock on the entry. It exists to allow callers to integrate state into a larger operation.

Parameters:

pentry	[INOUT] cache entry to operate on
state_type	[IN] state to be defined
pstate_data	[IN] data related to this state
powner_input	[IN] related open_owner
pcontext	[IN] FSAL credentials
ppstate	[OUT] pointer to a pointer to the new state
pstatus	[OUT] returned status

Returns:

the same as *pstatus

Definition at line 126 of file nfs4_state.c.

int state_conflict	(	state_t *	pstate,
		state_type_t	state_type,
		state_data_t *	pstate_data
	)

state_conflict : checks for a conflict between an existing state and a candidate state.

Checks for a conflict between an existing state and a candidate state.

Parameters:

pstate	[IN] existing state
state_type	[IN] type of candidate state
pstate_data	[IN] data for the candidate state

Returns:

TRUE if there is a conflict, FALSE if no conflict has been found

layout conflict is managed by the FSAL

Definition at line 72 of file nfs4_state.c.

state_status_t state_del	(	state_t *	pstate,
		state_status_t *	pstatus
	)

state_del: deletes a state from the hash's state

Deletes a state from the hash's state

Parameters:

pstate	[OUT] pointer to the new state
pstatus	[OUT] returned status

Returns:

the same as *pstatus

Definition at line 363 of file nfs4_state.c.

state_status_t state_del_locked	(	state_t *	pstate,
		cache_entry_t *	pentry
