函数名称：从文件系统上获得索引节点

函数原型：struct inode *iget5_locked(struct super_block *sb, unsigned long hashval, int (*test)(struct inode *, void *), int (*set)(struct inode *, void *), void *data)

返回类型：struct inode

参数：

类型参数名称
struct super_block *sb
unsigned longhashval
int (*test
int (*set
void *data
1143  inode等于在高速缓存查找索引节点
1145  如果非inode则
1146  new等于alloc_inode(sb)
1148  如果new则
1149  Misc 等于0
1150  inode等于de_insert5 - obtain an inode from a mounted file system*@inode: pre-allocated inode to use for insert to cache*@hashval: hash value (usually inode number) to get*@test: callback used for comparisons between inodes*@set: callback used to initialize a new
1151  如果此条件成立可能性小(为编译器优化)(inode != new)则destroy_inode(new)
1155  返回:inode
