测试方法：
①将fstest版本放到/home/wxt目录下解压后编译
[root@host10242493 pjd-fstest-20080816]# pwd
/home/wxt/pjd-fstest-20080816
[root@host10242493 pjd-fstest-20080816]# make
gcc -Wall ${CFLAGS} fstest.c -o fstest
[root@host10242493 pjd-fstest-20080816]# ls
fstest fstest.c LICENSE Makefile README tests
[root@host10242493 pjd-fstest-20080816]# cd tests
[root@host10242493 pjd-fstest-20080816]# pwd
/home/wxt/pjd-fstest-20080816/tests
②切换到/mnt/data目录（测试目录）下，执行：prove -r /home/wxt/pjd-fstest-20080816/tests
cd /mnt/data
prove -r /home/wxt/pjd-fstest-20080816/tests
