[ros-kernel] Media change support

[Eric Kohl]

Hi all!

I guess I have found a way to support media changes. Rajeev Nagar describes
the media change support in his boot 'Windows NT File System Internals' in a
very strange way that does not show the whole picture.

The most important thing is that the first step is missing: An FSD's
CreateFile routine must issue an IOCTL_XXX_CHECK_VERIFY request to the
storage device in order to find out whether the medium was changed. If that
request returns STATUS_VERIFY_REQUIRED call IoVerifyVolume.

In Nagar's book the media change information seems to fall from the sky.
That's why the reader does not find a starting point for his/her
implementation.

Does it seem to make sense? Hartmut?

Eric
