From 5c81691bb6461a474ac9d6ad5737c12e8f558a8b Mon Sep 17 00:00:00 2001 From: Akira Yokosawa Date: Fri, 26 Nov 2021 13:11:17 +0900 Subject: 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.
