Description Yongcheng Yang 2015-10-29 06:52:39 UTC 
Description of problem:
When using "exportfs -u" to unexport just one directory, it always return 0 even if unexport failed actually.

Version-Release number of selected component (if applicable):
nfs-utils-1.2.3-64.el6

How reproducible:
100%

Steps to Reproduce:
1. exportfs -u no_exit:/export/
2. echo $?

Actual results:
[root@ibm-x3650m4-08 ~]# exportfs -v
[root@ibm-x3650m4-08 ~]# exportfs -u no_exit:/export/
[root@ibm-x3650m4-08 ~]# echo $?
0
[root@ibm-x3650m4-08 ~]#

Expected results:
Don't return 0 if unexport failed
