From a42bcaabb63722411bee52b80cbfc795593defbc Mon Sep 17 00:00:00 2001 From: Martin Schwenke Date: Mon, 19 Aug 2019 21:47:03 +1000 Subject: ctdb-daemon: Factor out new function ctdb_node_become_inactive() This is a superset of ctdb_local_node_got_banned() so will replace that function, and will also be used in the NODE_STOP control.
