v7 looks good to me, test passes on ppc64 hosts too, thanks!

But it seems that it's not decided yet whether xfs should trim the
ranged fiemap query request, I'd like to see the expected behavior
decided first. (BTW, v7 passes with latest RHEL7 kernel too, seems
extents are not trimmed there.)

Thanks,
