Forwarding of completed WDFREQUESTs?

NTDEV
1

I need some request context’s data for a while after completion, and since request contexts can be kept around (by upping refcount), can the WDFREQUEST object be still forwarded/requeued to queues? Or maybe after completion I should treat it as a usual WDFOBJECT?

You can’t put it back into a queue since we need the PIRP for that and now it is gone upon completion. Treat it like a wdfobject and only ref/deref/get the context in this state
