With recent dd and 2.4.17rc1 an attempt to write (with DD)
into a block-device yields EINVAL error.

Doing strace shows that it comes from ftruncate64()
on the opened device.

Should there be some other error code ? EBLKDEV ?
Or is the dd (4.0p) at fault, and it should either
not ask for the ftruncate*() at all, or ignore its error ?
