Oleg, This patch probably needs review for any races we may have missed to account for. Also we have considered only workqueue.c present in 2.6.20-rc6-mm3, which means some recent patches in mm tree which are yet to be published arent accounted for.
Also I expect almost all worker threads to be frozen "for hotplug". The only exception I have found so far is kthread workqueue, which needs to remain unfrozen "for cpu hotplug" because kthread_create (in CPU_UP_PREPARE and stop_machine) relies on its services (while everyone else is frozen).
