--- Comment #14 from Amit Chaurasia <achauras at redhat.com> ---
Marking the bug verified as I didn't see any hang or crash anywhere while all
the operations worked seamlessly.

But, there is another issue that I observed.

When the quota was not enabled, the IO was happening through dd without any
issue, but as I enabled quota, the file handle was lost and the dd stopped.

The error was : 

[root at dht-rhs-19 test_dir]# dd if=/dev/urandom of=testfile bs=1024
count=10000000 

dd: writing `testfile': No data available
dd: closing output file `testfile': No data available
[root at dht-rhs-19 test_dir]# 



And the dd operation would exit intermittently after quota was enabled. 

[root at dht-rhs-19 test_dir]# dd if=/dev/urandom of=testfile-1 bs=1024
count=10000000 
dd: writing `testfile-1': No data available
dd: closing output file `testfile-1': Numerical result out of range
[root at dht-rhs-19 test_dir]# 
[root at dht-rhs-19 test_dir]# 


I am filing another bug for this issue. 
But marking this bug as verified as didn't see any memory issue.
