一个关于警告的问题....

今天我在用find命令查找一个文件的时候,出现了下面这种警告,不知道是出了什么问题,望高手告之...
[root@localhost ~]# find / -name 练嘴篇
find: WARNING: Hard link count is wrong for /proc: this may be a bug in your fil esystem driver. Automatically turning on find's -noleaf option. Earlier result s may have failed to include directories that should have been searched.
先谢谢了!!
