I have two questions about FltUnregisterFilter:
1. Is it possbile that minifilter is unregistered between a pre and corresponding post calls? how can i free CompletionContext if post callback is skipped because of driver unloading.
2. Does system free all allocated stream contexts and stream handle contexts allocated by my minifilter during FltUnregisterFilter call? i assume yes, can someone confirm?
