During logical hotplug, you only get the hotplug notifiers. During physical hotplug, you get the subsys_remove.

From Rafael's mail it looked like we also get hotplug notifiers..

So it will be hoplug notifier followed by subsys, and that would be a special case then..

So, we have all the information needed to distinguish. Remove the sysfs entries only in subsys-remove.

But hotplug notifiers would have already done most of the work we wanted. And this will be a special case then.

Also, a policy might be shared by multiple CPUs and we need to take that into account as well here..

So, not that straight forward as I can see it..

Also, are you aware of any way to emulate that ?
