I'm afraid it won't be committed without the second patch as without a single user of cpu_hotplug_enable/cpu_hotplug_disable (among modules) this patch doesn't make much sense. I would rather expect both of them to go through Greg's tree but with proper sign-offs/reviewed-bys. And of course this decision is up to tree maintainers, I'll resubmit the vmbus patch in case CPU hotplug patch gets committed separately. Thanks, > > Regards, > > K.
