Summary: The change contains a bunch of additional asserts that verify some assumptions on which mounting relies on. Working on the previous diffs I realized that it's very easy to broke those and then spend hours trying to understand what exactly went wrong. Changelog: [Internal] Fabric-specific internal change.
