| |
Hi, I am trying to implement a watchdog driver in 2.6.23 for the i.MXL cpu (based off of drivers/char/watchdog/s3c2410_wdt.c).
I had a question about the api doc for the watchdog (Documentation/watchdog-api.txt). Line 37 says "When the device is closed, the watchdog is disabled." Later on (Line 56) it says "Drivers will not disable the watchdog, unless a specific magic character 'V' has been sent /dev/watchdog just before closing the file."
I would assume that from reading L37 that the driver would unconditionally shut down the watchdog when closing (unless CONFIG_WATCHDOG_NOWAYOUT or the nowayout module param is specified), but line 56 seems to contradict that.
Can you clarify the intended behaviour?
