From 266aa1c4b3d004123d330eb412cc26a3d10f9029 Mon Sep 17 00:00:00 2001 From: Wim Van Sebroeck Date: Fri, 19 Aug 2005 23:31:41 +0200 Subject: [PATCH] [WATCHDOG] driver-for-ibm-automatic-server-restart-watchdog-fix2.patch The device/watchdog has a fixed timeout/heartbeat. So we don't support the WDIOC_SETTIMEOUT ioctl call and we also may not set the WDIOF_SETTIMEOUT flag.
