 *
 * We use regexes to parse the line into three separate pieces:
 * 1) The directory (exports.h -- DIRECTORY_REGEX_PATTERN)
 * 2) The netgroup if it exists (exports.h -- NETGROUP_REGEX_PATTERN)
 * 3) The host if it exists (exports.h -- HOST_REGEX_PATTERN)
 *
 * In this case, the netgroup would be @test(sec=sys,rw,anonuid=0)
 * and the host would be hostA(sec=sys,rw,anonuid=0).
 *
 * @line        : The line to parse
 * @dir         : Double pointer to the struct we need to parse the line into.
 *                If the parsing failed, the struct will point to NULL,
 *                otherwise it will point to a valid memory region that is
 *                allocated by this function.
 * @parse_full  : This parameter tells us whether we should parse all the lines
 *                in the file, even if they are not present in gluster's config.
 *                The gluster config holds the volumes that it exports so
 *                if parse_full is set to FALSE then we will ensure that
 *                the export file structure holds only those volumes
 *                that gluster has exported. It is important to note that
 *                If gluster exports a volume named '/test', '/test' and all
 *                of its subdirectories that may be in the exports file
 *                are valid exports.
 *  @ms         : The mount state that holds the list of volumes that gluster
 *                currently exports.
 *
 * @return : success: GF_EXP_PARSE_SUCCESS on success, -EINVAL on bad arguments,
 *                    -ENOMEM on memory allocation errors,
 *                    GF_EXP_PARSE_LINE_IGNORING if we ignored the line,
 *                    GF_EXP_PARSE_ITEM_FAILURE if there was error parsing
 *           failure: NULL
 *
 * The caller is responsible for freeing memory allocated by this function
 * The caller should free this memory using the _exp_dir_deinit () function.
 *
 * Not for external use.
