Looks good, just a minor comment:

i wouldn't break the format string like that. Doing:

			fprintf(stderr,
	_("specified blocksize %d is less than device physical sector size %d\n"),
				blocksize, ft.psectorsize);

Is consistent with long format strings elsewhere in the xfsprogs
code, and it makes grepping easy. Same for each of the other long
format strings you broke in half...

Other than that, consider it:
