函数名称：grity_inode_get - find or allocate an iint associated with an inode*@inode: pointer to the inode*@return: allocated iint* Caller must lock i_mutex

函数原型：struct integrity_iint_cache *integrity_inode_get(struct inode *inode)

返回类型：struct integrity_iint_cache

参数：

类型参数名称
struct inode *inode
98  struct rb_node * node, * parent = NULL
101  iint等于grity_iint_find - return the iint associated with an inode
102  如果iint则返回:iint
105  iint等于分配高速缓存区
106  如果非iint则返回:NULL
109  write_lock( & integrity_iint_lock)
111  p等于rb_node
112  当p循环
113  parent等于p
114  test_iint等于rb_entry(parent, structintegrity_iint_cache, rb_node)
116  如果inode小于ack pointer to inode in question 则p等于rb_left
118  否则p等于rb_right
122  ack pointer to inode in question 等于inode
123  node等于d in integrity_iint_tree
124  i_flags或等于Inode has an associated IMA struct
125  rb_link_node(node, parent, p)
126  rb_insert_color(node, & integrity_iint_tree)
128  write_unlock( & integrity_iint_lock)
129  返回:iint
