If I move the clear_bit() call inside the #ifndef, then when
CONFIG_WATCHDOG_NOWAYOUT is defined, after a process closes /dev/watchdog, no
process will ever be able to open it again. Are you saying that once
wd_keepalive exits, you don't want anyone to be able to open /dev/watchdog and
ping the timer again?
