inode则反映了文件系统对象中的一般元数据信息。dentry则是反映出某个文件系统对象在全局文件系统树中的位置。 Linux对这四种数据结构进行了相关的关联。 如下图: 1. 超级块(super block) 超级块:一个超级块对应一个文件系统(已经安装的文件系统类型如ext2,此处是实际的文件系统,不是VFS)。
The file has been recovered! Delete with care It may be either comforting or disconcerting that the file you deleted withrmisn't actually gone. Recovery depends on prior knowledge of a file's inode location or a brute-forcesearch-and-recoverywithspecialized tools. ...
