watchdog: stop watchdog first on startup
Some watchdog implementations may do things other than issue a reboot on a watchdog timeout. In this case, there's the possibility of restarting this program from the state of the watchdog device not being properly stopped (done by writing a 'V' and closing the device). Since it wasn't stopped, the driver may not be able to restart the watchdog when this program reopens it and starts pinging it. To fix this, the code will always first issue the stop when it starts up. function old new delta shutdown_on_signal - 32 +32 watchdog_main 268 298 +30 shutdown_watchdog - 25 +25 watchdog_shutdown 41 - -41 ------------------------------------------------------------------------------ (add/remove: 2/1 grow/shrink: 1/0 up/down: 87/-41) Total: 46 bytes Signed-off-by: Matt Spinler <spinler@us.ibm.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
