[Qemu-devel] [PATCH v5 5/5] iotests: chown LUKS device before qemu-io launches

["Daniel P. Berrange" <berrange@redhat.com>]

On some distros, whenever you close a block device file
descriptor there is a udev rule that resets the file
permissions. This can race with the test script when
we run qemu-io multiple times against the same block
device. Occasionally the second qemu-io invocation
will find udev has reset the permissions causing failure.
