How reproducible:

Always

Steps to Reproduce:
1.Create a volume and mount it via ganesha on 2 clients.
2.Start creating files from both the clients.
3.Once creation is done on one client, do an ls -ltr on that client.
4.Observe that as soon as you issue an ls on one client, file creations gets
hanged on other client.
5.Also, ls -ltr doesn't gives any output. See below:

[root at dhcp46-206 nfs1]# ls -ltr
total 0
[root at dhcp46-206 nfs1]# 


Actual results:

So there are 2 issues here.
1) ls on one client hangs file creation on other client.
2) ls -ltr doesn't give expected output.

Expected results:

There should not be any hangs and ls output should be as expected.
