Thanks for the updated version. Could you maybe also add a couple of additional tests
with charge_quota = TRUE? Since you are changing both versions, I'm fearing a bit that
your changes could break other situations. If there are no unexpected test failures it
looks good to me.

Thanks for your review.
An updated version of test and change is attached to the bug [1].
With my crosstest exe this testbot run was started [2].

I tried to run the test in a 64bit VM but got just blue screens with 
MULTIPLE_IRP_COMPLETE_REQUESTS.
Are the driver test framework patches supposed to succeed on 64bit windows?

Kind regards,
Bernhard
