This patch set addresses various races in relation to CPU hotplug and a race in relation to watchdog timer expiry. I discovered the corner cases during code inspection. I haven't seen any of these issues occur in practice.
Ulrich Obergfell (4): watchdog: avoid race between lockup detector suspend/resume and CPU hotplug watchdog: avoid races between /proc handlers and CPU hotplug watchdog: remove {get|put}_online_cpus() from watchdog_{park|unpark}_threads() watchdog: fix race between proc_watchdog_thresh() and watchdog_timer_fn()
