Function Documentation

int handle_mapping_hash_add	(	hash_table_t *	p_hash,
		uint64_t	object_id,
		unsigned int	handle_hash,
		fsal_handle_t *	p_handle
	)

Definition at line 194 of file handle_mapping.c.

int HandleMap_DelFH

(

nfs23_map_handle_t *

p_in_nfs23_digest

)

Remove a handle from the map when it was removed from the filesystem or when it is stale.

Definition at line 383 of file handle_mapping.c.

int HandleMap_Flush

(

)

Flush pending database operations (before stopping the server).

Definition at line 423 of file handle_mapping.c.

int HandleMap_GetFH	(	nfs23_map_handle_t *	p_in_nfs23_digest,
		fsal_handle_t *	p_out_fsal_handle
	)

Retrieves a full fsal_handle from a NFS2/3 digest.

Parameters:

p_nfs23_digest	[in] the NFS2/3 handle digest
p_out_fsal_handle	[out] the fsal handle to be retrieved

Returns:

HANDLEMAP_SUCCESS if the handle is available, HANDLEMAP_STALE if the disgest is unknown or the handle has been deleted

Definition at line 324 of file handle_mapping.c.

int HandleMap_Init

(

const handle_map_param_t *

p_param

)

Init handle mapping module. Reloads the content of the mapping files it they exist, else it creates them.

Returns:

0 if OK, a posix error code else.

Definition at line 249 of file handle_mapping.c.

int HandleMap_SetFH	(	nfs23_map_handle_t *	p_in_nfs23_digest,
		fsal_handle_t *	p_in_handle
	)

Save the handle association if it was unknown.
