If you would rather handpick the specific commits that had deviations, please
let me know and I can list them. Since 18.04 is a long term release it would
help to be in sync with the upstream set of patches to avoid back porting
issues in the future. Please let me know if you have questions/concerns. Thanks
a LOT !
