[PATCH 0/4] watchdog: address various races (CPU hotplug, timer expiry)

[Ulrich Obergfell]

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()
