I don't think they get it wrong, they are just reporting what the
drive says over that interface.

I ... don't actually know where smartctl/hdparm get the values, vs.
the values exported to blockdev.  Is the drive reporting different
values over different query interfaces?  Hrm.

mkfs.xfs uses the same interface as used by blockdev.
