Re: [Drbd-dev] [PATCH] docs: admin-guide/blockdev: Use subgraphs in node-states-8.dot

Thanks for catching this, Akira.

Unfortunately, this fix causes the "node_states" and "peer_states"
graphs to be mixed up. I guess this happens because the same IDs are
used in each subgraph. The graphs should be separate.

On reflection, the digraph node_states can be removed entirely. It is
too basic to contain any useful information. In addition it references
"ioctl_set_state". The ioctl configuration interface for DRBD has long
been removed. In fact, it was never in the upstream version of DRBD.

Best regards,
Joel
