It seems to work fine for me, tested with a modified sd that doesn't
have barrier support and loop:

Filesystem "sdc1": Disabling barriers, trial barrier write failed
XFS mounting filesystem sdc1

and

Filesystem "loop0": Disabling barriers, trial barrier write failed
XFS mounting filesystem loop0

No extra failure warnings on the barrier IO itself. What device do you
see this on?
