I would argue that his patch corrects a regression introduced by the
patch series.  Before the series, 'reboot' worked properly without the
watchdog being loaded as a module.  With this patch series 'reboot'
stops functioning which I would argue is a regression.  Making the
watchdog part of the kernel fixes the broken reboot regression.  I
would request it be accepted.
