Subject: [PATCH] docs: admin-guide/blockdev: Remove digraph of node-states
While node-states-8.dot has two digraphs, the dot(1) command can
not properly handle multiple graphs in a DOT file and the
kernel-doc page at
https://www.kernel.org/doc/html/latest/admin-guide/blockdev/drbd/figures.html
fails to render the graphs.
It turned out that the digraph of node_states can be removed.
Quote from Joel's reflection:
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.
Remove node_states and rename the DOT file peer_states-8.dot.
