Hmm... Sorry, am I facing different review-points from 3 different XFS maintainers? ...

Dave: require_no_largefs is better.
Darrick: nearly ack this patch.
Eric: 
2018-04-27 04:03 < sandeen> [15:01]  <zoro> [00:55:47] I think maybe use _require_no_large_scratch_dev for xfs/002 will be better. Grow a 128M XFS to large size is 'horrible'
2018-04-27 04:03 < sandeen> just limit growfs to something smaller.

What should I do next?

Thanks,
Zorro
