fsal_status_t XFSFSAL_DigestHandle	(	fsal_export_context_t *	p_expcontext,
		fsal_digesttype_t	output_type,
		fsal_handle_t *	handle,
		struct fsal_handle_desc *	fh_desc
	)

FSAL_DigestHandle : Convert an xfsfsal_handle_t to a buffer to be included into NFS handles, or another digest.

Parameters:

output_type	(input): Indicates the type of digest to do.
in_fsal_handle	(input): The handle to be converted to digest.
fh_desc	(input/output): The buffer where the digest is to be stored. On input fh_desc->len is set to the size of the buffer, on return fh_desc->len is used to indicate how many bytes have been copied into the buffer at fh_desc->start.

Returns:: The major code is ERR_FSAL_NO_ERROR is no error occured. Else, it is a non null value.

		fsal_digesttype_t	in_type,
		struct fsal_handle_desc *	fh_desc
	)

FSAL_ExpandHandle : Verify handle - mostly used to check that the size matches.

Parameters:

in_type	(input): Indicates the type of digest to be expanded.
fh_desc	(input/output): The handle built from digest.

Returns:: The major code is ERR_FSAL_NO_ERROR is no error occured. Else, it is a non null value.

unsigned int XFSFSAL_Handle_to_HashIndex	(	fsal_handle_t *	handle,
		unsigned int	cookie,
		unsigned int	alphabet_len,
		unsigned int	index_size
	)

FSAL_Handle_to_HashIndex This function is used for hashing a FSAL handle in order to dispatch entries into the hash table array.

Parameters:

p_handle	The handle to be hashed
cookie	Makes it possible to have different hash value for the same handle, when cookie changes.
alphabet_len	Parameter for polynomial hashing algorithm
index_size	The range of hash value will be [0..index_size-1]

Returns:: The hash value

int XFSFSAL_handlecmp	(	fsal_handle_t *	hdl1,
		fsal_handle_t *	hdl2,
		fsal_status_t *	status
	)

FSAL_handlecmp: Compare 2 handles.

Parameters:

handle1	(input): The first handle to be compared.
handle2	(input): The second handle to be compared.
status	(output): The status of the compare operation.

Returns:

- 0 if handles are the same.

A non null value else.
Segfault if status is a NULL pointer.

fsal_status_t XFSFSAL_load_FS_specific_parameter_from_conf	(	config_file_t	in_config,
		fsal_parameter_t *	out_parameter
	)

FSAL_load_FSAL_parameter_from_conf, FSAL_load_FS_common_parameter_from_conf, FSAL_load_FS_specific_parameter_from_conf:

Those functions initialize the FSAL init parameter structure from a configuration structure.

Parameters:

in_config	(input): Structure that represents the parsed configuration file.
out_parameter	(ouput) FSAL initialization structure filled according to the configuration file given as parameter.

Returns:: ERR_FSAL_NO_ERROR (no error) , ERR_FSAL_NOENT (missing a mandatory stanza in config file), ERR_FSAL_INVAL (invalid parameter), ERR_FSAL_SERVERFAULT (unexpected error) ERR_FSAL_FAULT (null pointer given as parameter),

Definition at line 412 of file FSAL_XFS/fsal_tools.c.

fsal_status_t XFSFSAL_SetDefault_FS_specific_parameter ( fsal_parameter_t * out_parameter )

Those routines set the default parameters for FSAL init structure.

Returns:: ERR_FSAL_NO_ERROR (no error) , ERR_FSAL_FAULT (null pointer given as parameter), ERR_FSAL_SERVERFAULT (unexpected error)
