Christian Brauner b3679e8b59 fs: add is_idmapped_mnt() helper ... commit bb49e9e730 upstream. Multiple places open-code the same check to determine whether a given mount is idmapped. Introduce a simple helper function that can be used instead. This allows us to get rid of the fragile open-coding. We will later change the check that is used to determine whether a given mount is idmapped. Introducing a helper allows us to do this in a single place instead of doing it for multiple places.
