struct inode *inode
struct qstr *name
2142  found等于d_hash_and_lookup - hash the qstr then search for a dentry*@dir: Directory to search in*@name: qstr of name we wish to find* On lookup failure NULL is returned; on bad name - ERR_PTR(-error)
2143  如果found则
2144  放置一个索引节点
2145  返回:found
2147  如果d_in_lookup(dentry)则
2148  found等于d_alloc_parallel( parent directory , name, in-lookup ones only )
2150  如果是错误或非d_in_lookup(found)则
2151  放置一个索引节点
2152  返回:found
2154  否则
2155  found等于分配高速缓存区
2156  如果非found则
2157  放置一个索引节点
2158  返回:错误号
2161  res等于链接目录项
2162  如果res则
2163  dput - release a dentry*@dentry: dentry to release * Release a dentry. This will drop the usage count and if appropriate* call the dentry unlink method as well as removing it from the queues and* releasing its resources
