函数原型：void audit_log_n_string(struct audit_buffer *ab, const char *string, size_t slen)

返回类型：void

参数：

类型参数名称
struct audit_buffer *ab
const char *string
size_tslen
1946  如果非ab则返回
1949  BUG_ON(!rmatted skb ready to send )
1950  skb等于rmatted skb ready to send
1951  avail等于缓存区尾部字节
1952  new_len等于slen加3
1953  如果new_len大于avail则
1954  avail等于audit_expand - expand skb in the audit buffer*@ab: audit_buffer*@extra: space to add at tail of the skb* Returns 0 (no space) on failed expansion, or available space if* successful.
1955  如果非avail则返回
1958  ptr等于skb_tail_pointer(skb)
1959  ptr自加等于'"'
1960  内存复制(ptr, string, slen)
1961  ptr加等于slen
1962  ptr自加等于'"'
1963  ptr等于0
1964  设置数据在缓存区
