From 58872d5f367876a81dcda82465381d80d321a81d Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Tue, 16 Jun 2009 10:30:35 +0200 Subject: [PATCH] [S390] pm: vmwatchdog power management callbacks. This patch implements suspend/hibernation for the vmwatchdog driver. The pm_notifier_callchain is used to get control on PM events. Since watchdog operation and suspend cannot work together in a reliable fashion, the open flag is also used to prevent suspend and open from happening at the same time. The watchdog can also be active with no open file descriptor. This patch adds another flag which is only changed in vmwdt_keep_alive and vmwdt_disable.
