fsal_status_t CEPHFSAL_DigestHandle	(	fsal_export_context_t *	extexport,
		fsal_digesttype_t	output_type,
		fsal_handle_t *	exthandle,
		struct fsal_handle_desc *	fh_desc
	)

Create a wire level representation of an FSAL handle.

Convert an fsal_handle_t to a buffer to be included into NFS handles, or another digest.

Parameters:

extexport	[in] The export context
output_type	[in] The type of digest requested
exthandle	[in] The handle to be digested
fh_desc	[out] Counted buffer to hold the handle

Returns:: Errors as appropriate

fsal_status_t CEPHFSAL_ExpandHandle	(	fsal_export_context_t *	extexport,
		fsal_digesttype_t	in_type,
		struct fsal_handle_desc *	fh_desc
	)

Bring in a wire handle.

All we do here is adjust the descriptor length based on knowing the internals of struct file_handle and let the upper level handle memcpy, hash lookup and/or compare. No copies anymore.

Parameters:

extexport	[in] The export handle
in_type	[in] The type of digest to be expanded
fh_desc	[in,out] Descriptor for buffer

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

unsigned int CEPHFSAL_Handle_to_HashIndex	(	fsal_handle_t *	exthandle,
		unsigned int	cookie,
		unsigned int	alphabet_len,
		unsigned int	index_size
	)

Generate an index in the handle table.

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

Parameters:

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

Returns:: The hash value

unsigned int CEPHFSAL_Handle_to_RBTIndex	(	fsal_handle_t *	exthandle,
		unsigned int	cookie
	)

Generate a hash to locate the handle within a tree.

This function is used for generating a RBT node ID in order to identify entries into the RBT.

Parameters:

exthandle	[in] The handle to be hashed
cookie	[in] Makes it possible to have different hash value for the same handle, when cookie changes.

Returns:: The hash value

int CEPHFSAL_handlecmp	(	fsal_handle_t *	exthandle1,
		fsal_handle_t *	exthandle2,
		fsal_status_t *	status
	)

Compare 2 handles.

This function compares two FSAL handles, returning 0 if they are to be considered identical.

Parameters:

handle1	[in] The first handle to be compared
handle2	[in] The second handle to be compared
status	[out] Status of the compare operation

Return values:

0	if handles are the same
Something	else if they're not

fsal_status_t CEPHFSAL_load_FSAL_parameter_from_conf	(	config_file_t	in_config,

	)

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),

fsal_status_t CEPHFSAL_SetDefault_FSAL_parameter ( fsal_parameter_t * out_parameter )

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