Hi again,

I've patched the NBD driver to set the physical sector size. Was way
easier than I imagined:

        }
 
+       /* Set physical block size to blocksize */
+       blk_queue_physical_block_size(lo->disk->queue, lo->blksize);
+
        while ((req = nbd_read_stat(lo)) != NULL)
                nbd_end_request(req);
 
----------------------------------------------------------------------

And I can confirm that the sector size detection is still broken in
3.1.7.
