File 0001-Shutdown-corosync-after-a-fatal-error.patch of Package pacemaker.16898

Subject: [PATCH] Shutdown corosync after a fatal error

If pacemaker shuts down due to being fenced by a non-power (eg fabric)
fence agent then it should also take down corosync so that full cluster
service on that node is lost, rather than just resource management.
