Yes, you're right. There is nothing different with DT_XYZ since
I followed what f2fs did when I wrote this place.
Actually, I noticed that patchset once in mailing list months ago
https://lore.kernel.org/r/20181023201952.GA15676 at pathfinder/
but I didn't keep eyes on it (whether this patchset is merged or not...)
OK, let me fix that like other fses. Thanks for pointing out.
Thanks,
