Problem with Workitem

NTFSD
1

Hi All,

If I queue a workitem in InstanceSetup and before the workitem get chance to execute if InstanceTeardownComplete occur then what happens with workitem?
Does it executes or removed from queue as device object is destroyed?

Because in InstanceSetup I have queued a workitem in which I signal a event and I am waiting on that event in InstanceTeardownComplete. But some times I am not able to unload the driver. I suspect that the event is not set as workitem does not get execute and so InstanceTeardownComplete gets blocked.

Thanks & Regards,
Amit.

My understanding is that these things take a reference count on the instance
object. So, yes, the instance teardown start will be called; but the
teardowncomplete wont be called until you delete the workitem which will in
turn dereference the instance object.
