Comment 5 for bug 1757107

All of the changes in https://anonscm.debian.org/cgit/pkg-mysql/mariadb-10.1.git/diff/debian/?id=ubuntu/10.1.30-0ubuntu0.17.10.1&id2=debian/10.1.25-1 are packaging wise necessary minimum changes for the security update to work (e.g. refreshing patches, applying a FTBFS patch, adopt to upstream build artifact changes due to use of --fail-missing).

The debdiff you attached shows other changes. I am trying to find out how that happened.
