If you look at my patch, you will see that is precisely what it does.
As the comments indicate, it uses the exact same check as ext4, which
will correctly refuse to mount huge volumes on 32-bit systems.

The XFS test appears to be the same thing written a little
differently. Andreas is suggesting that somebody should factor out
this check into a common library routine. That sounds like a fine
idea, but it also sounds orthogonal to the (simple and useful) patch I
am attempting to submit.
