Not that I can see... looking at 'git blame' for osi_vfsops.c
(afs_statfs), it looks like that line was changed in Linux by f3cd6ca0
(adding linux 2.6 support), in Solaris by 872bc94f, and then by the
initial IBM commit, and that's it. For darwin, we already do set it to
basically what I said. Unless I'm looking at the wrong thing...
