函数名称：在高速缓存查找索引节点

函数原型：struct inode *ilookup5(struct super_block *sb, unsigned long hashval, 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
unsigned longhashval
int (*test
void *data
1364  again :
1365  inode等于lookup5_nowait - search for an inode in the inode cache*@sb: super block of file system to search*@hashval: hash value (usually inode number) to search for*@test: callback used for comparisons between inodes*@data: opaque data pointer to pass to @test
1366  如果inode则
1367  writeback.h requires fs.h; it, too, is not included from here.
1368  如果此条件成立可能性小(为编译器优化)(inode_unhashed(inode))则
1369  放置一个索引节点
1370  转到:again
1373  返回:inode

名称描述
iget5_locked从文件系统上获得索引节点
bdev_unhash_inodeIf there is a bdev inode for this device, unhash it so that it gets evicted* as soon as last inode reference is dropped.
