函数名称：Called with the inode lock held.

函数原型：static struct inode *find_inode(struct super_block *sb, struct hlist_head *head, int (*test)(struct inode *, void *), void *data)

返回类型：struct inode

参数：

类型参数名称
struct super_block *sb
struct hlist_head *head
int (*test
void *data
817  struct inode * inode = NULL
819  repeat :
821  如果i_sb不等于sb则继续下一循环
823  如果非test(inode, data)则继续下一循环
825  加自旋锁
826  如果Misc 按位与I_FREEING按位或I_WILL_FREE的值则
827  __wait_on_freeing_inode(inode)
828  转到:repeat
830  如果此条件成立可能性小(为编译器优化)(Misc & I_CREATING)则
831  自旋锁解锁
832  返回:错误号
834  __iget(inode)
835  自旋锁解锁
836  返回:inode
838  返回:NULL
