superblock

The superblock is a structure that represents a file system .

超级块结构表示一个文件系统。

This links to the superblock structure , which I 'll explore next .

它链接下面讨论的超级块结构。

The superblock is the container for high-level metadata about a file system .

超块（superblock）是关于文件系统的高级元数据的容器。

One important element of the superblock is a definition of the superblock operations .

超级块中的一个重要元素是超级块操作的定义。

On disk , the superblock provides information to the kernel on the structure of the file system on disk .

在磁盘上，超块向内核提供关于磁盘上的文件系统的结构的信息。

At the root of each file system is the superblock , which describes and maintains state for the file system .

超级块在每个文件系统的根上，超级块描述和维护文件系统的状态。

In memory , the superblock provides the necessary information and state to manage the active ( mounted ) file system .

在内存中，超块为管理活动的（已挂载）文件系统提供必要的信息和状态。

The superblock is typically stored on the storage medium but can be created in real time if one doesn 't exist .

超级块通常存储在存储媒体上，但是如果超级块不存在，也可以实时创建它。

The superblock is a structure that exists on disk ( actually , multiple places on disk for redundancy ) and also in memory .

超块是存在于磁盘上（实际上位于磁盘的多个位置上，以提供冗余）的结构。

These objects are the superblock , inode , dentry , and file .

这些对象是超级块（superblock）、inode、dentry和文件。

A file system will have one root dentry ( referenced in the superblock ), this being the only dentry without a parent .

文件系统有一个根dentry（在超块中引用），这是唯一没有父对象的dentry。

This section explores the superblock , the index node ( or inode ), the directory entry ( or dentry ), and finally , the file object .

这个小节探索了超块（superblock）、索引节点（或inode）、目录条目（或dentry）和文件对象。

This takes a single argument defining the reference to a file system structure ( file_system_type ), which defines the name of the file system , a set of attributes , and two superblock functions .

这个函数的参数定义一个文件系统结构（filesystemtype）的引用，这个结构定义文件系统的名称、一组属性和两个超级块函数。

It doesn 't take much to make a superblock dirty , cause fragmentation , mess up inodes , or cause repeating JFS errors in the errpt .

无需多费劲就可以让超块变脏、造成存储碎片、搞乱存储节点或引起errpt反复出现JFS错误。

The list of these objects refers to the superblock and defines the mount point , name of the / dev device on which this file system resides , and other higher-level attachment information .

这些对象的列表引用超块，并定义挂载点、文件系统所在的/dev设备的名称以及其他高级附加信息。
