XFS correctly orders the cache flushes for it's different
devices to ensure integrity. e.g. it flushes the caches of the data
device which contains the filesytsem metadata before it issues the
the FUA write to the external log device.
And it does all the right cache flushes for both data and real-time
devices on fsync to ensure data updates are stable, too.
Cheers,
Dave.
