This breaks 512 byte and 1k block size filesystems.

$ head -3 139.full
Invalid value 8388608 for -d agsize option. Value is too small.
Usage: mkfs.xfs
/* blocksize */         [-b size=num]
$

Minimum AG size is 16MB. There are more changes to other tests in
this series that also demonstrate this regression.

Cheers,

Dave.
