qemu/tests/qemu-iotests/153.out
Max Reitz f45b638f9f iotests: Add creation test to 153 
This patch adds a test case to 153 which tries to overwrite an image
(using qemu-img create) while it is in use.  Without the original user
explicitly sharing the necessary permissions (writing and truncation),
this should not be allowed.
