Each entry in the list represents a mounted file system object.
Linux权限模型每个文件系统对象有3种类型。
The Linux permission model has three types of permission for each filesystem object.
没有执行权限，目录下的文件系统对象就是不可访问的。
Without execute permission, the filesystem objects inside a directory are not accessible.
更有益的是运用这些知识，这样就可以指定您要访问的文件系统对象。
What's more useful is to use this knowledge so you can specify filesystem objects that you want to access.
确定一个文件或目录的文件系统对象的路径是否是有效的。
Determines whether a path to a file system object such as a file or directory is valid.
这样使得您可以为文件系统对象建立细粒度的访问控制，并且支持继承特性。
This allows you to establish fine-grained access control for file system objects and support inheritance features.
文件系统对象的每个唯一的装入实例通过一个虚拟文件系统结构进行表示。
Each unique mount instance of a file system object is represented by a virtual file system structure.
此函数用来获取文件系统对象的信息，比如文件，文件夹，目录，驱动器根目录。
This function retrieves information about an object in the file system, such as a file, a folder, a directory, or a drive root.
每一个重要的内核对象，比如每个文件系统对象和每个进程，都有一个关联到它们的“安全上下文(security context)”。
Every critical kernel object, such as every filesystem object and every process, has a "security context" associated with them.
作为ClearCase的附加产品，ClearCaseMultiSite提供了可靠的存储着所有文件系统对象(无论是二进制的还是文本的)的资料库副本——跨地域。
As an add-on product for ClearCase, ClearCase MultiSite provides reliable replication — across geographies — of repositories storing any file system object, whether binary or textual.
每个文件系统都有自己的独特属性，比如大小写敏感性和支持的对象类型。
Each file system has its own unique attributes, such as case sensitivity, and allowed types of objects.
系统上的对象可以是文件、文件系统、卷组、设备等。
Objects on a system could be files, file systems, volume groups, devices, and more.
其他的对象，比如文件系统的图像或文件的情况与此相同。
The same can be said for other objects, such as images or files from the filesystem.
对象要备份到的文件系统目录。
The directory in the file system to which the objects are to be backed up.
inode表示文件系统中的一个对象，它具有惟一标识符。
The inode represents an object in the file system with a unique identifier.
如果消息表明成功，来自返回消息的信息将填充到structstat对象，从而使用来自虚拟文件系统的记录数据取代真实的数据。
If the message indicates success, information from the returned message gets stuffed into the struct stat object, replacing the real data with the recorded data from the virtual file system.
Ceph不只是一个文件系统，还是一个有企业级功能的对象存储生态环境。
Ceph is not only a file system but an object storage ecosystem with enterprise-class features.
注意，dentry对象仅存在文件系统内存中，而不能储存在磁盘上。
Note that the dentry objects exist only in file system memory and are not stored on disk.
帮助对象包括缓存管理(Cache对象)和用于发现应用程序源文件改变的内部文件系统监控器。
Helper objects include the cache manager (the cache object) and the internal file system monitor used to detect changes in the source files that form the application.
根目录条目(dentry)对象也缓存在这里，因为它是文件系统所在的块设备。
The root directory entry (dentry) object is cached here also, as is the block device on which this file system resides.
Linux以一组通用对象的角度看待所有文件系统。
Linux views all file systems from the perspective of a common set of objects.
Linux通过一个称为inode (indexnode的缩写)的对象管理文件系统中的所有对象。
Linux manages all objects in a file system through an object called an inode (short for index node).
dentry引用super_block, super_block定义包含该对象的特定文件系统实例。
The dentry refers to the super_block, which defines the particular file system instance in which this object is contained.
从存储角度来看，Ceph对象存储设备执行从对象到块的映射(在客户端的文件系统层中常常执行的任务)。
From a storage perspective, Ceph object storage devices perform the mapping of objects to blocks (a task traditionally done at the file system layer in the client).
Linux文件系统保存文件和其他对象（例如符号链接、类似磁盘的设备和目录），并分组归类到各个目录（其他操作系统称为文件夹）中。
Linux filesystems hold files and other objects (e.g. symbolic links, devices like disks, and directories) grouped into directories (known as folders on other operating systems).
在对象系统中，使用对象表示文件系统的所有元素。
From there, objects are used to represent all the elements of the file system.
今天，我们发现一种新的日志结构文件系统，并看到一个文件系统被引入到对象存储上。
Today, we find a new log-structured file system and the introduction of a file system over an object store.
这样一来，就更容易迁移到对象级存储，因为提供的文件系统本身是传统的文件系统。
In this way, it's easier to migrate to object-level storage, because the file system presented is a traditional file system.
