WDF IoTarget ClosedForQueryRemove

How does an IoTarget get in the WdfIoTargetClosedForQueryRemove state?

My driver never calls WdfIoTargetCloseForQueryRemove.

The IoTarget has an EvtIoTargetQueryRemove callback which unconditionally
returns STATUS_UNSUCCESSFUL.

Thanks,

It appears that calling WdfIoTargetClose temporarily sets the state to
WdfIoTargetClosedForQueryRemove. So, my problem appears to be a
synchronization issue between I/O issued to my target and my call to close
the target.
