The plan is to reimplement GetFreeDiskSpace on top of
NtQueryVolumeInformationFile, which should fix the issue since it will
require opening a handle to the directory. The equivalent in your test
program would be to open /mnt/cdrom and do a fstatvfs on the resulting
file descriptor. Could you verify if this does the right thing for
you?
