I don't think that can happen - you can only bread with i_blksize, and the
set_blocksize() stuff refuses to set to smaller than the hardware sector
size.

See

        /* Size cannot be smaller than the size supported by the device */
        if (size < get_hardsect_size(dev))
                return -EINVAL;

in set_blocksize().
