On Linux anyway, the way it's used here is pretty
pointless anyway. It passes either 0 or 1, which
means either don't set it (if "living dangerously")
or do set it, to the minimum XFS sector size, 512
bytes. Hence it'll screw up on > 512-byte sector
If there was a reason for setting it, it should
do so by setting it to the device's logical block
size rather than assuming 512.
But I don't see a reason to set it either, so the
change looks good to me.
