函数名称：moyo_read_group - Read "struct tomoyo_path_group"/"struct tomoyo_number_group"/"struct tomoyo_address_group" list.*@head: Pointer to "struct tomoyo_io_buffer".*@idx: Index number.* Returns true on success, false otherwise.* Caller holds tomoyo_read_lock().

函数原型：static bool tomoyo_read_group(struct tomoyo_io_buffer *head, const int idx)

返回类型：bool
