> Deadlock - in exactly the same way as with the xprt code...
Soooory! Delete from the picture all except for containing QDIO:
(Call QDIO bottom half code)
spin_lock(&QDIO_lock);
<QDIO hard interrupt>
->spin_lock(&QDIO_lock)
(spins...)
with the same result. No help of nfs is required. :-)
So, you have drawn wrong picture.
