2.6.32-stable review patch. If anyone has any objections, please let us know.
------------------
From: Josef Bacik <josef@redhat.com>
commit e3acc2a6850efff647f1c5458524eb3a8bcba20a upstream.
This patch revert's commit
6c090a11e1c403b727a6a8eff0b97d5fb9e95cb5
Since it introduces this problem where we can run orphan cleanup on a volume that can have orphan entries re-added. Instead of my original fix, Yan Zheng pointed out that we can just revert my original fix and then run the orphan cleanup in open_ctree after we look up the fs_root. I have tested this with all the tests that gave me problems and this patch fixes both problems. Thanks,
