This is harmless but the commit that makes this necessary is the commit
that allows unprivileged changes to the user namespace in 3.8 Aka:

    commit 0c55cfc4166d9a0f38de779bd4d75a90afbe7734

        vfs: Allow unprivileged manipulation of the mount namespace.

So I believe this is a useless backport.
