Description Vijaikumar Mallikarjuna 2015-08-05 04:47:53 EDT
Consider below scenario
1) rename FOP invoked on file 'x'
2) write is still in progress for file 'x'
3) rename takes a lock on old-parent
3) write-update txn blocked on old-parent
4) in rename_cbk, contri xattrs are removed and contribution is deleted and lock is released
5) now write-update txn gets the lock and updates the wrong parent
