It looks like the current version of xfsprogs (v4.3.0) has an inconsistency
between its documentation and implementation that is making the xfstest
xfs/293 fail:

./check xfs/293
FSTYP         -- xfs (debug)

"help" and "zero" are indeed options in xfs_io, but aren't listed in the man
page.

Thanks,
