After the commits for userspace (see Link tags below) the uuid field is not being used in the ACRN code. Update kernel to reflect these changes, i.e. do the following: - adding a comment explaining that it's not used anymore - replacing the specific type by a raw buffer - updating the example code accordingly The advertised field confused users and actually never been used. So the wrong part here is that kernel puts something which userspace never used and hence this may confuse a reader of this code. Note, that there is only a single tool that had been prepared a year ago for these forthcoming changes in the kernel.
