unmount hanging purging quotas
Hi Chandra,
I'm seeing xfs/050 hanging on a current oss-xfs master tree during unmount getting stuck purging dquots. it basically loops there forever. Have you seen anything like this recently?

FYI, I also ran into the same issue with 050 against mainline Linux-3.11-rc1 this afternoon, the latest commits of XFS is:
commit c31ad439e8d111bf911c9cc80619cebde411a44d
Author: Chandra Seetharaman <[email protected]> Date: Wed Jul 10 18:00:36 2013 -0500
xfs: Fix the logic check for all quotas being turned off

Hi Chandra,
I'm seeing xfs/050 hanging on a current oss-xfs master tree during unmount getting stuck purging dquots. it basically loops there forever. Have you seen anything like this recently?
I have been running xfstests successfully with CONFIG_XFS_DEBUG turned on in every patchset I have posted recently, and I have not seen any difference in behavior between the tree without my patchset and with my patchset.
One difference I see is that one of my patches is not in the tree yet.
I will test with the master tree as it is and report back.

Hi Dave,
I am not able to reproduce the problem with both oss-master and linus-master. I ran xfs/050 in a loop for 100 times with both the kernels, and they ran fine.
Now I am running the whole suite.
