I will add my hotplug changes on the top of these. And yeah, removing the warnings from thaw_processes sounds like a good thing to me. I was constantly getting warnings like "Strange, but ksoftirqd/1 was not frozen" when ksoftirqd was created in the CPU_UP path from the frozen context! I was wondering if freezing the processes created from the frozen context is a good thing to silence these warnings, but I guess that would open up some new races. > > Greetings, > Rafael regards gautham. -- Gautham R Shenoy Linux Technology Center IBM India.
