I'm not sure we've had any fixes for (or reports of) that issue since the v4.2 timeframe. What is the xfs_info of the associated filesystem? Also, do you have any insight as to the possible reproducer application or workload? Is this reproducible at all? Note that this is a WARN_ON_ONCE(), so the warning won't fire again regardless until after a reboot.
