other info that might help us debug this:

Chain exists of:
  &ocfs2_sysfile_lock_key[INODE_ALLOC_SYSTEM_INODE] --> &ocfs2_quota_ip_alloc_sem_key --> &ocfs2_sysfile_lock_key[ORPHAN_DIR_SYSTEM_INODE]

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
