Function Documentation

int fsal2posix_openflags	(	fsal_openflags_t	fsal_flags,
		int *	p_posix_flags
	)

fsal2posix_openflags: Convert FSAL open flags to Posix open flags.

Parameters:

fsal_flags	(input): The FSAL open flags to be translated.
p_hpss_flags	(output): Pointer to the POSIX open flags.

Returns:

- ERR_FSAL_NO_ERROR (no error).

• ERR_FSAL_FAULT (p_hpss_flags is a NULL pointer).
• ERR_FSAL_INVAL (invalid or incompatible input flags).

fsal_status_t posix2fsal_attributes	(	struct stat *	p_buffstat,
		fsal_attrib_list_t *	p_fsalattr_out
	)

Converts POSIX attributes (struct stat) to FSAL attributes (fsal_attrib_list_t)

int posix2fsal_error

(

int

posix_errorcode

)

posix2fsal_error : Convert POSIX error codes to FSAL error codes.

Parameters:

posix_errorcode

(input): The error code returned from POSIX.

Returns:

The FSAL error code associated to posix_errorcode.

Todo:

: The EBADF error also happens when file is opened for reading, and we try writting in it. In this case, we return ERR_FSAL_NOT_OPENED, but it doesn't seems to be a correct error translation.

Warning:

AIX returns EEXIST where BSD uses ENOTEMPTY; We want ENOTEMPTY to be interpreted anyway on AIX plateforms. Thus, we explicitely write its value (87).

Variable Documentation

uint32_t open_fd_count

This is a global counter of files opened by cache_inode. This is preliminary expected to go away. Problems with this method are that it overcounts file descriptors for FSALs that don't use them for open files, and, under the Lieb Rearchitecture, FSALs will be responsible for caching their own file descriptors, with interfaces for Cache_Inode to interrogate them as to usage or instruct them to close them.
