A user
A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running computation, block while waiting for an event, or read files from the file system. Unlike kernel drivers, a user-space device driver can use other device drivers--that is, access the network, talk to a serial port, get interactive input from the user, pop up GUI windows, or read from disks. User-space drivers implemented using FUSD can be much easier to debug it is impossible for them to crash the machine, are easily traceable using tools such as gdb, and can be killed and restarted without rebooting even if they become corrupted. FUSD drivers don t have to be in C--Perl, Python, or any other language that knows how to read from and write to a file descriptor can work with FUSD. User-space drivers can be swapped out, whereas kernel drivers lock physical memory.-A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running comput

模拟Unix文件系统
每一个文件系统不仅包括文件和数据，还包括文件系统本身的树形目录结构，以及子目录、链接、访问权限等信息，它还必须保证数据的安全性和可靠性。 Unix文件系统调用主要包括：文件的打开和关闭、文件的创建和删除，文件的连接和解除连接，文件的读和写，以及文件的随机访问。用户可以通过文件系统提供的系统调用在其程序中对文件进行上述操作。
