Just FYI - generally, the patch changelog goes below the "---"
so it doesn't end up as part of the changelog in git.

Is there any other case in mkfs where options are automatically disabled?
I don't think so .. I'd just prefer a failure here, not a fix-up, even
with the warning. But I guess that's how it was before, so probably
not something to change in this patch. So never mind. :)
But, do we need the extra indentation?
if (sb_feat.finobt && sb_feat.finobtflag) {
fprintf(stderr,
_("warning: finobt not supported without CRC support, disabled.\n"));
}
sb_feat.finobt = 0;
would suffice as before, no? Meh. Not a big deal I guess....
