684  i等于转换字符串为无符号整形
685  如果cp不等于'-'则返回:负EINVAL
687  data等于cp加1
688  profile等于moyo_assign_profile - Create a new profile.*@ns: Pointer to "struct tomoyo_policy_namespace".*@profile: Profile number to create.* Returns pointer to "struct tomoyo_profile" on success, NULL otherwise.

701  如果非new_comment则返回:负ENOMEM
703  加自旋锁
704  old_comment等于comment
705  comment等于new_comment
706  自旋锁解锁
