Tetsuo Handa 0d7a4e6589 cgroup,freezer: hold cpu_hotplug_lock before freezer_mutex in freezer_css_{online,offline}() ... commit f0cc749254d12c78e93dae3b27b21dc9546843d0 upstream. syzbot is again reporting circular locking dependency between cpu_hotplug_lock and freezer_mutex. Do like what we did with commit 57dcd64c7e036299 ("cgroup,freezer: hold cpu_hotplug_lock before freezer_mutex").
