Dear all,

       I have encountered a strange problem that the ownership of linkto file was changed to root:root after we reboot server. And I reproduced the problem many times.

For example: ff_2

First, the new created file: ff_2

[root at test02 ~]# ll /testfs/mydir

-rw-rw-r-- 1 test  test 5242880 Jan 12 11:31 f_4
-rw-rw-r-- 1 test  test    0 Jan 12 11:38 ff_1
-rw-rw-r-- 1 test test 5242880 Jan 13 00:43 ff_2
