Doc Text:	When quota is enabled on a pre-existing data, quota-crawl process starts healing the xattrs. During this process when a write operation is performed when healing is not complete, directory count can be missed on a directory. This causes an error in the 'quota list-objects'. With this release, the issue is fixed.	Story Points:	---

Description Vijaikumar Mallikarjuna 2015-07-16 10:46:08 UTC

Consider below scenario:

Quota enabled on pre-existing data
Now quota-crawl process will start healing xattrs
Now if write is performed where healing is not complete, there is a possibility that 'update txn' is started before 'create xattr txn', in this case dir count can be missed on a dir where quota size xattr is not yet created.
