This is a patch series that follows up the patch [1] after
the review from Daniel P. Berrange.

The new interface is being implemented only by the LUKS driver
because this is the error condition I'm trying to fix. My first
idea when coding it was to implement this interface in all drivers
that deals with local files, but I thought it would be overkill -
at least for this second spin.

Hi,

This series failed the docker-mingw@fedora build test. Please find the testing commands and
their output below. If you have Docker installed, you can probably reproduce it
locally.

Not sure why it complained about this. Travis didn't care ....


How can I reproduce this docker use test? I have a Fedora29 box with 
Docker and
issuing "make docker-test-mingw(...)" as mentioned above doesn't work.


Thanks,

I could reproduce the above error on my Fedora 29 x86_64 machine. From 
the build dir, run as:

make docker-test-mingw@fedora SHOW_ENV=1 J=14 NETWORK=1

Compile QEMU sources with default configs also fails.
