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()
